During the coronavirus crisis, the presence of experts in policy-making was on vivid display. The corona situation was extraordinary. Experts are often less visibly present in political life and in the public sphere in normal times, and it is well known how experts are consulted more, and more easily rise to power, in times of crisis. A plethora of experts are asked for policy advice all the time, and not only on corona and other health issues. Political processes leading up to decisions about tax and pension reforms, new environmental policies, educational policies, family policies, or policies in almost any other domain are often crowded with people with expert knowledge. Experts may also be so locked into their disciplinary culture that they fail to see the limitations of their own intellectual perspective or the value of competing approaches.
