At this moment of massive uncertainty, with data and analyses shifting daily, honest disagreements among academic experts with different training, scientific backgrounds, and perspectives are both unavoidable and desirable. It’s the job of policymakers, academics, and interested members of the public to consider differing point of views and decide, at each moment, the best courses of action. A minority view, even if it is ultimately mistaken, may beneficially temper excessive enthusiasm or insert needed caveats. This process, which reflects the scientific method and the culture that supports it, must be repeated tomorrow and the next day and the next.

Scientific consensus is important, but it isn’t uncommon when some of the most important voices turn out to be those of independent thinkers, like John Ioannidis, whose views were initially doubted. That’s not an argument for prematurely accepting his contestable views, but it is a sound argument for keeping him, and others like him, at the table.
