Double standards

Extracted from the Wikipedia article Double standard.
Causes and explanations
Double standards are believed to develop in people's minds for a multitude of possible reasons, including: finding an excuse for oneself, emotions clouding judgement, twisting facts to support beliefs (such as confirmation biases, cognitive biases, attraction biases, prejudices, or the desire to be right). Human beings have a tendency to evaluate people's actions based on who did them.
