A bias where one systematically invalidates sources of opposing information—attacking credibility, questioning motives, dismissing expertise—rather than engaging the information itself. Invalidation Bias doesn't need to refute claims; it just needs to discredit the source. If the source can't be trusted, the information doesn't need to be considered.
"He never addressed her arguments—just attacked her credentials, her funding, her personal life. Invalidation Bias: when you can't beat the message, discredit the messenger. The information remains unaddressed, but that's the point. Invalidate first, think never."

Get the invidation mug.An invalidator is any person who is, for whatever reason, prone to being jealous and insecure. In order to think well of themselves, they will say and do whatever they can to harm the target of their jealousies and insecurities, and to discredit them in any way they can. This gives them a false sense of self-worth and superiority. They are all about bringing out the worst in others, and they will use any unscrupulous, malicious, or manipulative tactic in order to achieve this end.
The best ways to confront an invalidator may include simply ignoring them, proving their accusations to be false, or to respond to their negativity with kindness or humor.
