I have a different way to look at this question. (1) introspection is bunk (2) if someone asks us or we ask ourselves why we did something - the answer is a guess, because we have no conscious access to the actual causes of our thoughts and actions (3)we vary in how good we are at guessing and in how honestly they judge themselves and so some people appear to be clearly rationalizing and other appear less so (4) most people are not actually aware that introspection is not direct knowledge but guesswork and so they do not recognize their guesses as guesses but may notice their self-deceptions as deceptions (5) we do not need to know the reasons for our actions unless we judge them as very bad and to be avoided or very good and to be encouraged (6) the appropriate thing in this case is not to ask ourselves why, but to ask ourselves how to change the likelihood of a repeat, up or down. Although we have only guesses about past actions, we can arrange to have some control over future ones (7) the more we know about ourselves, others, our situations, science and so on the better we can answer the how questions.

Good, upvoted - your hypothesis is interesting. I tend to think of type 1 as the cognition/pattern recognition/thinking operation and type 2 as a way of sequentially combining type 1 sub-results. The sequentially operation involves working memory and therefore passes through consciousness and is slowed down. As soon as a group of type 1 operations fine-tune themselves to the point of not requiring working memory, they no longer generate type 2 operations.

SaidAchmiz asked for an opinion and I gave an honest one. I may be wrong in the view of some other people but that is still my honest opinion. It is not an overgeneralization as I believe that in all cases, in all situations, at all times the descriptive approach is preferable to the prescriptive one.

In all cases 1-6 - descriptive is scientific, productive, interesting while prescriptive is without evidence, harmful and boring.

OK, I over reacted. Several others have said that it is acceptable in Main - so be it. I guess it does not bother others as much as it bothers me and I won't comment on corrections in future.

Doesn't anyone think that it is very rude to comment in someone else's language unless it is not understandable - just plain RUDE? If someone wants help with language they can ask. Language is a tool not a weapon.

Voting up and waiting for your next installment. (dtz weird text still there)

Why not adopt the convention used in many types of writing? The first time the term is used in a text, it is written in full and its abbreviation or acronym is put after it in brackets. After that the short form is used.

Thank you for the link - very illuminating.
