Coronavirus: Behaviour scientists hit back at Dominic Cummings criticism
SAGE advisers hit back at Dominic Cummings’s claim that No10’s first lockdown last spring came too late because of ‘crisis fatigue’ fears as behavioural experts say adviser is WRONG and were clear it should NOT influence policy
- Members of psychologist group SPI-B said they never tried to delay lockdown
- Mr Cummings said Downing Street was afraid people wouldn’t obey for long
- He said the past year had shown the ‘crisis fatigue’ claim to be ‘obviously wrong’
- SPI-B members said their explanation was never intended to be anti-lockdown
Dominic Cummings was today branded a liar by No10’s top behavioural scientists for accusing them of being opposed to lockdown rules in March last year.
The former No10 adviser claimed in an explosive meeting with MPs that members of a SAGE sub-group were wrong because they suggested long lockdowns wouldn’t work due to ‘fatigue’ that would see people give up on sticking to restrictions.
A meeting in March last year saw advisers on the SPI-B panel warn that restrictions may be harder to enforce over longer periods of time but experts admitted there was little evidence.
Boris Johnson repeated in his pre-lockdown press conferences in March 2020 that he wanted to make sure decisions were taken ‘at the right time’ and not too soon.
Mr Cummings today said the assumption that people would tire of obeying the rules was ‘obviously completely wrong’.
Members of SPI-B today hit back at Cummings’s claim and said he ‘does not appear to understand the role of SPI-B not the contribution of behavioural scientists’.
One member said SPI-B made it clear fears about crisis fatigue should not be taken as the group’s view nor used as an influencing factor in Government decisions.
A SPI-B file from March 12 showed the group was worried it would be portrayed this way and said: ‘We are concerned our comments about the difficulty of maintaining behaviours should not be used as a reason for not communicating with the public about the efficacy of the behaviours.’

Ex-No10 adviser Dominic Cummings claimed in a meeting with MPs that members of SAGE sub-group SPI-B were wrong because they suggested long lockdowns wouldn’t work due to ‘fatigue’ that would see people give up on sticking to restrictions – members of the group have hit back and said that was never their argument
Professor Susan Michie, a psychologist at University College London and member of the Scientific Pandemic Insights Group on Behaviours said today: ‘Cummings does not appear to understand the role of SPI-B nor the contribution of behavioural scientists on that group.
‘SPI-B is not asked to comment, and has not commented, on what interventions are effective or when they should be triggered.
‘Instead, the group is asked to provide advice aimed at anticipating and helping people adhere to interventions that are recommended by medical or epidemiological experts.
‘It also considers the likely or possible impact of various measures or scenarios.’
She added the group had made it clear that ’empirical evidence was limited’.
The retort was echoed by Professor John Drury, a psychologist at the University of Sussex, who added: ‘Cummings implicated SPI-B in the flawed fatigue rationale for delaying measures against the pandemic… the SPI-B paper from March 2020 clarifies that fatigue should not be an interpretation of any SPI-B recommendations.’
SPI-B includes psychologists and social scientists advises the Government on how people think, behave and might react to certain situations.
It warned in a meeting on March 13 that ‘experience suggests it is harder to comply with a challenging behaviour over a long period than over a short period’ – but admitted there was no evidence in the context of lockdowns.
Minutes from the meeting read: ‘There is some evidence that people find quarantining harder to comply with the longer it goes on.
‘The evidence is not strong but the effect is intuitive. There is no comparable evidence for social distancing measures, but experience suggests it is harder to comply with a challenging behaviour over a long period than over a short period.
‘There is no strong evidence for public compliance rates changing during a major emergency. There is, however, a link between public anxiety and protective behavioural change.
‘Difficulty maintaining behaviours should not be treated as a reason for not communicating with the public about the efficacy of the behaviours and should not be taken as a reason to delay implementation where that is indicated epidemiologically.’
A separate file from March 12 said: ‘We are concerned that our comments about the difficulty of maintaining behaviours should not be used as a reason for not communicating with the public about the efficacy of the behaviours.’
Fellow SPI-B expert Professor Stephen Reicher, from the University of St Andrews, retweeted Professor Drury’s comment and said: ‘More evidence that behavioural scientists did not delay lockdown by invoking “behavioural fatigue”.’
Professor Chris Whitty, England’s chief medical officer, had publicly referred to the issue as ‘crisis fatigue’.
And it was used by some experts as an explanation for why the UK didn’t lock down sooner.
A consultant psychologist in London, Emma Citron, told the New Scientist in March last year: ‘If they ask people to self-isolate now and curtail public gatherings or they close schools, then people can become fed up with strictures and simply stop conforming to them.’
In Boris Johnson’s own TV speeches shortly before the first lockdown in March, he hammered home the importance of starting restrictions ‘at the right time’ to avoid doing them unnecessarily.
On March 9 the PM said: ‘While it is absolutely critical, it’s absolutely critical in managing the spread of this virus that we take the right decisions at the right time, based on the latest and best evidence.
‘So we must not do things which have no or limited medical benefit, nor things which could turn out to be counterproductive.’
Mr Cummings today slammed fears about the message and claimed they had slowed down Britain’s movement into lockdown, although he denied saying that SPI-B were ‘charlatans’.
He told MPs: ‘Just to correct that I didn’t say that everybody involved with SPI-B were charlatans and that’s not the case.
‘The problem is that in this field of behavioural science there are a lot of charlatans and anybody who’s been involved with the clinical world knows that the whole field is riddled with duff studies, memes that people believe are true but aren’t true, and there is no doubt whatsoever that there’s a critical part of the false groupthink.

‘One of the critical things that was completely wrong in the whole official thinking in SAGE and in the Department of Health in February and March was, first of all that the British public will not accept a lockdown, secondly the British public will not accept what was thought of as an East Asian-style track and trace type system and the infringements of liberty around that.
‘Those two assumptions were completely central to the official plan and were both obviously completely wrong.
‘In the first half of March this was raised sometimes in the Prime Minister’s office and me and others were literally pointing at the TV screen of Lombardy [Italy, the first part of Europe hit by the pandemic] and saying look at what’s happening in Lombardy.
‘We’re getting text messages on our own phones from our own families saying “what’s going on?”. This assumption that the public basically aren’t that frightened and don’t want to have a lockdown is false and we should abandon it.’
