RationalWiki's 2020 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone who saw this today donated $5, we would meet our goal for 2021.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $20 or whatever you can today with PayPal Logo.png!

An imprecision fallacy (also an error in sampling) occurs when evidence used is not representative, because it is imprecise in some way.

For example, in an apex fallacy, only the cream of the crop are considered when generalizing to all members of a group; clearly, the top performers are not representative, and so cannot be generalized.

It is an informal fallacy.
