It is difficult to be sanguine when people around you does something wrong with you. The wrong doing does not have to be extreme it could be as simple as a colleague not replying to your email when you expected them to reply. In many situations like these we tend to assume that other person does not want our good and they are doing it intentionally. The result of these explanations is that we strain our relations with people around us. We can’t read their mind but still we end up assuming what is in their mind. Hanlon’s razor mental model can help us overcome this bias.
