The Sir Tim Hunt affair: the science behind the saga

After publishing my blog post earlier this month on The Tim Hunt affair - a call for evidence-based judgement and decision making I was contacted by Professor Narinder Kapur who, like me, has an honorary position at University College London. Professor Kapur was interested in exploring some of the psychological perspectives of the case, and we agreed to collaborate on a short article which we offer below. We hope that this article will help to inform the debate by providing an understanding of the underlying behaviour involved.

Abstract
Sir Tim Hunt’s predicament following his remarks at an international conference caused major controversy. Here, we examine how psychology as a scientific discipline may inform an understanding of some of the behaviours which formed part of that controversy. We briefly note findings in relation to eye-witness memory, cognitive bias, humour, moral behaviour, communication and online discourse.

Introduction
Sir Tim Hunt, Nobel Prize Winner, found himself at the centre of media attention after he made remarks at a conference of science journalists in Korea in June 2015. He subsequently resigned from positions within University College London, the Royal Society, and the European Research Council (Hunt, Wikipedia entry, 2015).

This article considers ways in which findings from psychological research may help to understand aspects of the controversy.

1. Eye-witness memory

The event in question, and Sir Tim Hunt’s speech in particular, appears not to have been video-taped or audio-recorded in full, so it is difficult to be certain about errors relating to eye-witness memory. Nevertheless, there is now overwhelming evidence to show that eye-witness memory may be fallible (Lilienfeld and Byron, 2013; Loftus, 2013), that memory for conversations may be particularly liable to error in a number of ways (Davis et al., 2005; Hirst and Echterhoff, 2012), and that a high level of confidence in a memory may in fact be related to the falsity of a memory (Weinstein and Shanks, 2010). The evaluation of evidence by eye witnesses can be biased by existing beliefs (Snyder and Cantor, 1979), and memory for events can be readily distorted by such beliefs (Johnson et al., 2012).

2. Cognitive and affective biases

Judgmental and emotional statements were made by many individuals, including scientists, journalists and the general public via social media channels. Numerous books and articles have pointed to the presence of cognitive and affective biases, many of which may operate at an unconscious level (Sutherland, 2013; Kahneman, 2012; Sheeran et al., 2013). Individuals may not be aware of their bias ‘blind spots’, and higher cognitive ability has in fact been associated with a larger bias blind spot (West et al., 2012). In the ensuing debates relating to the controversy, there were many instances of confirmation bias, whereby evidence was sought out to support a particular point of view. More sophisticated forms of bias also appeared to occur – e.g. retrieval-induced forgetting, whereby repeated retrieval of a particular piece of information can result in suppression from memory availability of related information (Storm et al., 2015), appeared to be manifest in the repeated retrieval of the ‘sexist’ remarks by Sir Tim Hunt and the associated suppression of the remarks and actions in favour of women which seemed to characterise much of his career.

3. The psychology of humour

Sir Tim Hunt’s remarks at the conference were reportedly offered as humour, and it is how this humour was viewed that was a key part of the affair (Bishop, 2015). As Jarrett (2013) has pointed out, humour may have evolutionary benefits, and those who suffer a neurological condition, such as the Nobel Prize winner Sir Peter Medawar after his stroke, have pointed to a sense of humour as being one of the key survival and coping strategies (Kapur, 1997; Roger et al., 2014). Scott et al. (2014) have highlighted the social side of humour, where it is associated with bonding, agreement and affection. It is thus one way of communicating with others, be it an individual or an audience, and it may serve a dual function of imparting information and generating affection and commonality. Jarrett (2013) has alluded to possible sex differences in both the generation and appreciation of humour, and also how it has been used as an avenue for understanding conditions such as autism. Lockyer and Pickering (2009) have pointed to the limits of humour, and situations in which it may backfire. Ford and Ferguson (2004) have concluded that while in some cases disparagement humour may create a normative climate of tolerance to discrimination, in general exposure to such humour does not appear to reinforce negative images of the group that is the target of the disparagement. Riesch (2014) has reviewed the ways in which humour has been used in science communication, and UCL has in fact pioneered the Bright Club to use the medium of comedy to convey scientific messages (www.ucl.ac.uk/public-engagement/brightclub).

4. Moral behaviour

The controversy surrounding Sir Tim Hunt’s remarks included many moral judgments as to the righteousness of actions by Tim Hunt, by UCL and by those who spread news of his comments. It is possible to discern moral dilemmas faced by those who were put into certain positions and asked to make judgments. Researchers such as Haidt (2007) have highlighted the importance of moral intuitions, the social rather than the truth-seeking nature of moral thinking and the coevolution of moral minds with cultural practices and institutions. Some of the debate following Sir Tim Hunt’s remarks appeared to be divided along gender lines, and it is of note that Fumagalli et al. (2010) found gender-related differences in moral judgments, with men giving significantly more utilitarian answers to personal moral dilemmas. Baumard and Boyer (2013) have touched on the issue of proportionality of punishments in the context of moral behaviour, and how this appears to be a universal feature of interactions with a moral theme.

5. Communication

Lapses in communication between a wide range of individuals and organizations appeared to be one of the major features of the controversy. After considering the matter, UCL Council ordered a review of its communication strategy. Communication failures abound in all walks of life, from politics to patient safety. In the case of the latter, Kapur (2014) has, on the basis of relevant research studies, pointed to lessons that have been learned from studies of communication failures, and some of these lessons can probably be applied to the Sir Tim Hunt controversy. Thus, errors of communication are more likely to occur when – there are multiple, often contradictory, pieces of information from a range of sources; when there is time pressure; when there is high emotion; when there is ambiguity or duplication of roles; when there are authority gradients and where authority rather than evidence or reasoned decision-making determines the communication; where there is a culture that suppresses bad news and strives to put reputation before truth and transparency; and where there is mutual stereotyping between parties. Research has shown that seemingly innocuous sentences which contain implied emotion can result in what the authors termed ‘combinatorial processing’ and can readily activate emotion-related areas of the brain (Lai et al., 2015). Fischhoff (2013) has outlined four sets of expertise required for good science communication – subject matter scientists to get the facts right; decision scientists to identify the right facts that need to be communicated; social and behavioural scientists to formulate and evaluate communications; and communication practitioners to create trusted channels and modalities of communication. Uncertainties about facts and about predictions abound in science, as they did in the Sir Tim Hunt controversy, and both the recognition of such uncertainty, and ways of communicating in the presence of uncertainty, have been outlined by Fischhoff and Davis (2014).

6. The psychology of online discourse

It is widely acknowledged that online communication media such as Twitter played a key role in the transmission of messages after Sir Tim Hunt made his remarks. Domenico et al. (2013) have shown how the rapid spread of online communications via Twitter can be systematically modelled. Fenn et al. (2014) noted that false information acquired through Twitter was less likely to be integrated into a memory representation. There is greater potential for inflamed communications when these occur online (2015), and this may be due to factors such as relative anonymity of participants and absence of direct body cues during such interactions.

23andMe genotypes one millionth customer

23andMe have today announced that they have genotyped their one millionth customer. The full press release can be read here. 23andMe have also sent out personal e-mails to all their customers advising them of their customer number. I am customer number 46,957. I was one of the early adopters in the UK. I couldn't afford to pay the then price of $499 but I took the opportunity to order a test for $99 when there was a flash sale on DNA Day in April 2010. There is a certain kudos to having a five-digit customer number but we do have a number of people in our genetic genealogy community in America who have four-digit numbers, and even some genetic genealogy pioneers with coveted three-digit numbers! I've copied below the e-mail that I received from 23andMe. The content of the e-mail is also reproduced on the 23andMe blog.

Debbie,

Last week, we genotyped our one millionth customer. You are part of the one million people driving change.

One million is more than a number. It's a turning point. We are taking control of our data. We are taking ownership of information about ourselves. We believe knowing more about who we are can benefit society, not just the individual.

Just fifty years ago, doctors were reluctant to tell patients if they had cancer.1 The world is different today.

One million customers ago, attendees were shocked at the annual American Society of Human Genetics conference when direct-to-consumer genetic testing services were announced.2

One million customers ago, we didn't know how consumers would react to direct-to-consumer testing, but now there are studies showing consumers don't overreact to their results.3

One million customers ago, we didn't have the Genetic Information Non-Discrimination Act in the United States or other personal data protection laws that are now in place in many countries around the globe.

One million customers ago, we didn't have direct access to our health laboratory results. The United States recently mandated individuals can get laboratory test results directly from the laboratory upon request.4

As customer number 46,957, you are part of this unique group of one million people driving change. I celebrate you, your 23andMe story and the power of all of us today: #PowerOf1Million.

You'll often overhear me enthusiastically telling people to "Spit!" but today is the day to be proud and let everyone know: "I Spat!"

Onward.

23andMe are now the first DNA testing company to reach the milestone of having one million people in a single database.

AncestryDNA are probably also very close to the one million mark. They currently state that they have 850,000 people in their database, but they have been citing this figure for some time. They have previously said that they are selling 150,000 kits per quarter. We can probably expect an announcement very soon.

Family Tree DNA were the first company to hit the one million milestone but their tally of one million test takers is spread across two different databases. FTDNA have their own proprietary database but they also do the testing for the Genographic Project. There is some overlap between the two databases as Genographic customers can transfer their results to the FTDNA genealogical matching database.

It's taken nearly eight years for 23andMe to reach the one million milestone but the big growth only started to take place when they dropped the price of their test to $99 in December 2012. I wonder how long we will have to wait before we see the first two million or five million consumer DNA database.

The AncestryDNA international roll-out, shaky leaves and AncestryHealth

The AncestryDNA test is now starting to be rolled out in other countries. The test was officially launched in the US in May 2012. It became available in the UK and Ireland in January 2015, and was launched in Australia and New Zealand at the end of May. The test became available in Canada this week. It is not known if Ancestry will sell the test in any other countries. They also have offices and a subscriber base in Sweden and Germany. Germany has restrictive laws on direct-to-consumer testing so it seems unlikely that the test will be offered there. However, Sweden might well be another target market for the company in the near future.

It is interesting to note that the AncestryDNA test is much more expensive outside the US, and it remains to be seen how this will impact the take up of the test in other countries. Here is a comparison of the prices.

US $99 + $9.95 for shipping = US $108.95
Australia and New Zealand AUS $149 + $29.99 for shipping = $178.99 or US $138
Canada CAN $149+ $19.95 for shipping = $168.95 or US $138.40
UK and Ireland £99 + £20 shipping = £119 or US $183

Note that we are paying much more for the test in the UK and Ireland than in any other country. However, Ancestry do have frequent promotions such as the current offer of 10% off for Father's Day so do look out for these special offers.

I put myself on the invitation list when the AncestryDNA test first came out in the US, and was able to order a test in June 2012 despite the fact that I don't live in America, though this loophole was quickly closed. The AncestryDNA database has grown at a phenomenal rate and by the end of March this year they had DNA results for over 850,000 people. However, with a database that has until this year been 99.9% American I've had very little out of the test so far. I have no known cousins in America. Nevertheless I have had a lot of matches but they are nearly all with very distant cousins with deep roots in Colonial America. They generally have no surnames or geographical locations in common with me and it would be an impossible task trying to find the genealogical connection in these circumstances.

Now that the first results are starting to come in from the UK the situation is changing and I'm pleased to report that I have my first ever shaky leafy hint at AncestryDNA which has enabled me to confirm a genealogical connection with a third cousin in the UK. The shaky leaf hints are well named because the leaf really does shake when you first see it! This is what my match page now looks like.


The predicted relationship for my new match was third to fourth cousin. When I click to view the match I get taken to a page where I can see the shared ancestor hint and an outline of our two trees showing our connection to the common ancestral couple, my great-great-grandparents Charles James Wiggins and Mary Ann Thorn. (I've blurred out the names of the recent generations in the screenshot below.)


In this particular case the shaky leaf hint has worked exceptionally well, and my match turned out to be a third cousin. Because it's a close relationship it probably would have been a straightforward matter finding the connection but it certainly helps having Ancestry doing all the hard work for you. I shall look forward to confirming more relationships as more results start to come back from the UK and Ireland. I also look forward to receiving matches with people in Australia, New Zealand and Canada, as I have a number of links with all three countries in my family tree.

The frustrating part of the AncestryDNA test is that there is no way of verifying the validity of the match. Ancestry do not provide the underlying segment data on which the match is based and they don't offer a chromosome browser. It is rather like being given access to an index and then finding that the key records that you want in the index have been withheld for no good reason and you are expected to rely instead on someone else's transcription. I am hoping to persuade my match to transfer her results to Family Tree DNA using the autosomal DNA transfer programme. I'm also hoping that she will be able to transfer her results to GedMatch. However, we should not have to rely on transferring our data to other websites in order to access such basic data. I hope that Ancestry will fix this issue as a matter of priority.

In another development Roberta Estes reports that Ancestry are now beta-testing a new AncestryHealth website in the US. Roberta has bravely volunteered as a guinea pig and tried out the new service. I suggest you read her blog post if you want to find out more. It remains to be seen if AncestryHealth will become available in other countries. It is not clear to me what benefits can be derived from such a service as it is not telling you anything that you didn't already know. There are already a number of free tools available online to calculate your risk of developing various conditions. Here are three examples that I found in a quick internet search: Stroke Risk Calculator, Diabetes Risk Calculator, and Oncolink. However, if I had a family history of a particular condition I would much rather go and visit my GP to determine my risk rather than input the information on a website. If I want to record my own health information online I can use a free service like the Microsoft HealthVault.

Although AncestryHealth is currently a separate entity from AncestryDNA you can import your family tree and also your ethnicity estimates from AncestryDNA. I noticed that the AncestryDNA Privacy Statement and Terms and Conditions were updated on 18th May and the changes take effect for existing customers from 18th June 2015. I have not received an e-mail from Ancestry advising me of these changes but the updates were visible when I checked into my AncestryDNA account. The Privacy Statement was also updated back in February 2015 though I don't recall noticing this update at the time. On comparing the different versions the biggest change I noticed was introduced back in February this year. AncestryDNA now make it explicitly clear that users' DNA results will be internally analysed not just for genealogical purposes but also for "medicine and other topics".

Here is the relevant clause from the old Privacy Statement dated 20th March 2013:
v) To Research the human genome. If you voluntarily agreed to the AncestryDNA Consent Agreement we may use the Results and other information in an aggregated and anonymous form, for the purposes of research and publication and in accordance with the AncestryDNA Consent Agreement.
Ancestry do state here that your DNA results can be used for research but the implication is that this will only happen if you voluntarily sign the AncestryDNA Consent Agreement. Contrast this clause with the updated Privacy Statement dated 20th February 2015:
vi) To perform research: AncestryDNA will internally analyze Users’ results to make discoveries in the study of genealogy, anthropology, evolution, languages, cultures, medicine, and other topics. In addition, if you voluntarily agreed to the Research Project Informed Consent we may use the Results and other information for the purposes of collaborative research and publication and in accordance with the Informed Consent.
If you sign up for AncestryHealth you are given the option to sign an Informed Consent form to participate in research. Similarly, if you take an AncestryDNA test you are also given the option to participate in research by signing an Informed Consent form. The wording of both forms is almost identical. Here is the description of the Research Project from AncestryDNA:
1. What is the research project?
The Ancestry Human Diversity Project collects, preserves and analyzes genealogical pedigrees, historical records, surveys, family health data, medical and health records, genetic information, and other information (collectively, "Information") from people all around the world in order to conduct research studies to better understand, among other things, human evolution and migration, population genetics, population health issues, ethnographic diversity and boundaries, genealogy, and the history of our species ("The Project"). Researchers hope that the Project will be an invaluable tool for a wide range of scholars interested in genealogy, anthropology, evolution, languages, cultures, medicine, and other topics and that the Project may benefit future generations.

Researchers hope that the Project will be an invaluable tool for a wide range of scholars interested in genealogy, anthropology, evolution, languages, cultures, medicine, and other topics, and that the Project may benefit future generations.
Many people will have signed the Informed Consent form on AncestryDNA without realising what they were doing as it is presented as just one extra box to be ticked to complete the order process, and it is easy to tick the box without even reading the form. I wrote of my concerns about this process when I activated my own kit back in 2012. At that time the research project was known as the Human Genome Diversity Project. As I was unable to find out any further information about what this project involved I did not sign the form and have still not done so.

I suspect many people who took the AncestryDNA test will be surprised to find that by submitting their DNA for a genealogical DNA test their results might also be used for medical research. I'm quite happy to have my DNA used for research purposes. I've tested at 23andMe, and I am participating in the UK Biobank Project which is sequencing the DNA of over 500,000 British people. However, if people's DNA results are to be used for medical research I do think that the process should be transparent and that informed consent should be obtained up front rather than changing the terms and conditions and the privacy policy and hoping that people won't notice.

Despite these concerns I do think it is worthwhile doing the AncestryDNA test. Ancestry have a big marketing machine and will inevitably attract customers who would not have considered taking a test anywhere else. However, if you are taking a test to confirm a specific hypothesis about relationships then the Family Finder test from Family Tree DNA is the most cost-effective option. The Family Finder test costs around £70 inclusive of postage versus £119 for the AncestryDNA test.

See also Sue Griffith's Notes for UK (and ex-US) residents on DNA testing companies where she provides advice and detailed costings on testing with all the different companies from a UK perspective.

The business of genetic ancestry


There is a programme going out next Tuesday 26th May on BBC Radio 4 on the "business of genetic ancestry". The programme is presented by Dr Adam Rutherford and includes interviews with Professor Mark Jobling from the University of Leicester, my colleague Professor Mark Thomas from University College London and yours truly! You can find further details about the programme here:

http://www.bbc.co.uk/programmes/b05vy4kb

The programme will also be available on the iPlayer and it will be repeated on Monday 1st June at 9pm.

I paid a visit to New Broadcasting House at the end of last month to record my interview with Adam. I was interviewed for one hour and 20 minutes, and we had a wide-ranging conversation about the exciting discoveries that can be made from DNA testing but also about some of the problematic press coverage and the dubious claims made by certain companies. Obviously only a tiny fraction of what I said will make the final cut, so I shall be interested to see how it turns out.
In the recording studio with Adam Rutherford.
I have been very impressed with the way that the programme has been made. The BBC have done a lot of research behind the scenes and have gone to great pains to talk to a wide range of people and to present a balanced view showing both the benefits of genetic ancestry testing but also highlighting some of the problematic areas. They invited people from all sides of the debate to contribute to the programme though I understand that unfortunately not everyone who was invited to participate chose to do so.

If you listen to the programme do let me know what you think.
