If you perceive yourself to be more logical and rational – than most others, or at least more than the average of others – then you might prepare yourself for continuous frustration at the limitations of others to also think in a logical and rational manner.
But an attitude of constantly expecting to be frustrated is unproductive and probably unhealthy.
First of all, though we might perceive ourselves to be logical and rational, we might be overestimating our own abilities. After all, it is human nature to be overcome by emotions, and we probably all very often act in ways that are contrary to what a disciplined decision-maker would do, based solely on evidence and reasoning.
Secondly, the appropriate mindset to take is the one that is most productive and positive. So do not dismiss, but instead, respect, acknowledge and value the contributions of others. This attitude encourages greater understanding of alternative perspectives, by considering the information that is available and why that leads to a particular view.
These considerations above do not in anyway negate the advantages and benefits to be gained from studying logic and reasoning; instead, they suggest a framework for how to most productively respond and interact with behavior that at first glance, seems irrational or illogical.
