Here's why:
* It often implies a self-deceptive process: Rationalization is used when someone tries to justify their actions or beliefs with logical reasons, even if those reasons are not the real ones. This can be seen as a way of avoiding responsibility or confronting uncomfortable truths.
* It can be seen as a defense mechanism: While we all rationalize to some degree, it can become problematic when used excessively. It suggests that the person is not truly facing their own motivations or the reality of the situation.
However, there are situations where "rationalization" can have a neutral or even slightly positive connotation:
* In a business context: It can refer to the process of making a decision based on logic and data, rather than emotion.
* In academic or scientific settings: It can refer to the process of analyzing and explaining phenomena in a logical and systematic way.
Overall, the connotation of "rationalization" depends heavily on the context. It is generally negative when it implies self-deception or avoiding responsibility, but it can be more neutral or even positive in certain specific situations.
