You must clearly state who, when, where, why, and what will be done. If you write a note to a subordinate, instructing them to do something, but fail to explain the reason, Brown might fire you because he is very clear that people are most likely to accept an idea only if the reasons for that idea are meticulously laid out.
Unfortunately, the tendency to value reasons is so powerful that even if the justification provided by a person is meaningless or inaccurate, it can make their commands and requests easier to comply with. A psychological experiment proved this point. In this experiment, the participant successfully cut in front of the long line waiting for the copier, giving the reason: “I need to copy a few things.” This unfortunate side effect of the tendency to value reasons is actually a conditioned reflex. This conditioned reflex occurs because most people believe that things with reasons are important. Naturally, certain commercial institutions and cult organizations often utilize various catchy justifications to achieve their hidden objectives.
