Looking around, if I distinguish between the very raitonal folks and the very irraitonal, a feeling emerges that both are inferior.
Many "rational" are living quite rtechnically. Many have a storng need for control, whihc makes them acting raitonal. But htier rationality is at least partly for other emotional reasons as the need to feel that they do always the right thing and the feeling of fully ocntrolling their lives.
But the main problem is the cost that obsessive rationality has. It makes life very effortful, and also avoids and depresses natural behavior and the expression and knowledge aobut one's emotions.
This is not rational. Because the idea of raitonality is to be rational because this is the best way ot get to one;s goals, not because one has side motives.
Others enjoy the ease of not looking for control. But pay the price with not being always rational, whihc may bear a truly heavy price.
Theoretically, it is possible to be rational in the right amount. That is not trying to control everything, but for the important things to be rational (or to be moderately rational on the smaller things. That is rational with the level of thoughts and effort compatible with the issue at hand, a challenging calibration).
There are ceratinly people with more balanced kinds of rationality.
But when a person tries delibarately to be more rational, or someone wants to teach others to be rational, one must consider this complexity. That sometimes being rational comes in a toxic way.
