"Facts don't care about your feelings." has a profound scientific background:
Irrationality.

I am absolutely convinced that irrationality is the core root of human social issues and dramatically underrated.
Therefore, I made a very short summary here:

Attention: If you think you are a master of your own cognitive biases, PLEASE CONTACT ME !!!

Irrationality is a cognitive science term.

Simply said it describes when, why and how logical/reasonable thinking and decisions are systematically influenced by impulses / emotions.
Such emotional forces can be momentary (eg. stress, aggression, arousal), genetically hardwired (eg. appetite, jealousy) or acquired (eg. attitudes, beliefs). On top of all that goes the ego of each individual as an omnipresent, subjective judge.

It is important to understand that such 'thinking' is unconscious and intuitive.

Examples

• favoring a leader/speaker for his personality traits rather than his contents
• favoring free product offers over others (regardless of actual benefit/price)
• using social media when it really ruins your life
• road rage
• taking rhino horn to improve potency
• practically everything women do on Tinder
