Fantastic question to ask yourself whenever you're in a heated or polarised debate, from the wise Carl Sagan, via the wise Helen Czerski. https://twitter.com/helenczerski/status/1347178217707335680

Also worth considering who told you the things you believe to be true, and what their evidence is.

A good rule of thumb, this time from Christopher Hitchens, is 'Extraordinary claims require extraordinary evidence.'

Those claiming widespread electoral fraud in 2020 have none.

There is great power in aphorisms: they are memorable, repeatable, and we retain them in a special part of our minds.

So here's another one from the humanist David Hume:

'A wise person proportions their beliefs to the evidence.'

Live by that motto and you won't go far wrong.
