«Errare humanum est»is a Latin phrase, but it is not fully reproduced in this form. The complete version of the expression is as follows: «Errare (Errasse) humanum est, sed in errare (errore) perseverare diabolicum.» (Hieronymus; Seneca, Epistulae morales VI,57,12; Cicero, Orationes Philippicae 12,2), which is translated as follows: «To err is human, but to insist on error is diabolical.» (Source)

The dispute between scientists and self-appointed experts about the current pandemic could hardly be described more accurately. But even scientists are not immune to error, as the Guardian plausibly describes in a recent article “We need scientists to quiz Covid consensus, not act as agents of disinformation”. We recommend you to read the article.

It comes to the conclusion that you should trust the science, not the scientists. They are just people who are subject to the same cognitive biases, the same whims of the ego as the rest of us. In the real world, the line between courageously questioning a rotten consensus and trying to suppress legitimate criticism of bad science can be very thin. It is a disturbing finding, but scientists can be gripped by anti-science just like anyone else.
