"Rationalization (psychology)

In psychology, rationalization is the process of constructing a logical justification for a decision, action or lack thereof that was originally arrived at through a different mental process.

This process can be in a range from fully conscious (e.g. to present an external defense against ridicule from others) to mostly subconscious (e.g. to create a block against internal feelings of guilt).

For an example, consider a person who bought one of the first home computers in 1980 primarily motivated by the excitement of playing with a computer. If he felt that his friends would not accept "having fun" as a sufficient reason for the purchase, he might have searched for other justifications and ended up telling them how much time it was going to save him in doing his taxes.

Rationalization is one of the defense mechanisms proposed by Sigmund Freud, which were later developed further by his daughter Anna Freud."

Siempre creí que si racionalizaba los hechos podría entender todas las cosas.

En más de una ocasión me he enfrentado a hechos que son lo que son, y la razón sólo sirve para dar fe y tomar nota, sin embargo siempre siento dentro de mí el impulso de encontrar un sentido y al mismo tiempo sé que debería olvidarlo. En esos casos, siempre cumplo un plazo más o menos prolongado de penitencia en el que trato de hallar razones, explicaciones, de construir una argumentación racional para algo que ni lo necesita, ni le corresponde. Luego, sencillamente, lo asumo.
