Simon Ruda, a behavioural scientist, said he feared the "most egregious and far-reaching mistake" made during the Covid-19 crisis was the "level of fear willingly conveyed on the public". "Though I don't think it's fair to blame behavioural scientists for propagating fear (I suspect that this was more to do with government communicators and the incentives of news broadcasters), it may be worth reflecting on where we need to draw the line."
