This sounds like a disease but its not. This isn't a real term either. Its just a name I have for the habitual use or insistent attachment of post rationalization. Post rationalization is the simple act of justifying your actions, after, you have done them. This is not something unusual at all. We do it all the time, sometimes knowingly and intentionally because we have some other priority at hand which is being satisfied, but mostly unconsciously. Its an energy saving mechanism of the mind, a tool that helps to avoid confusion and maintain composure.
In an beautifully simple experiment scientist used a magic trick called the black card trick to fool the subjects into accepting, after having rejected it, the wrong card yet at the same time exposing a very fundamental fact about our ability to make decisions and the very conviction with which we stand by them. The experiment involves showing two similar yet distinct pictures of the same person to the subject and asking which one they like better. They are asked twice to make sure they see the difference and choose with confidence. Just then, the experimenter puts the cards down on the table and behind each picture card is another card with the opposite picture, the experimenter slips the back card to the subject. The top of the actual card is black and the table is black too, so the experimenter simply slides back that card without the subject knowing. The subject picks up the card, looks at the picture and is as confident as before, even if there is slight inexplicable confusion it doesn't last long before the subject convinces himself that it is the card what he chose.
Making decisions is as common an activity as from drinking water to taking a breath. Depending on what you call a decision, you could be making from tens to hundreds of decisions per day. Some big and life changing to some small and insignificant, but decisions nonetheless. A common problem with making decisions in uncertainty, which in common parlance is called life, is that you cannot be sure that the decision you made is correct or not. So you spend sometime thinking about it, weigh in the pros and cons, look at the best and worst case, discuss it with an expert and finally make a decision. Not everyone goes to this length but that's pretty much as far as you go. Once the decision is made you either are right in the near future or dead embarrassed wrong. In the long term what a decision brings is once again a matter of uncertainty because you can only know as much time as you have spent. If its "long" term and becomes clear "someday" then until that time comes, probably few generation down the road by some people's standard, you wouldn't know.
In the post decision period if someone asks you about your reasons you either state the most obvious things you knew before making that decision or what you realized after it, with confidence, in your support. Unless the decision turns so bad that when it goes public its intensity multiplied by the number of people who come to know it , make it utterly impossible to consider right and you must accept your bad judgement and then backtrack or change direction. While its not that bad, the natural tendency is to believe that you made the right choice. It is reassuring and gives you a feeling of control over your life. You may accept the opposite card and you may convince yourself that it is what you "chose". So much for being in control and choosing how to live your own life. A generation's dream evaporated.
So what the hell do you do in the face of such absurd limitations of the very brain which you need to make decisions and lots and lots of them for a probably very long life to come? Just be aware of the fact. Those tricky scientists suggest that you try to be as conscious as possible of fact that you are making decisions in uncertainty and you may fooled by your own self in to believing something that is not. After that be ready to look at evidence that says you missed something and try not to insist too much on one answer when everything was not as clear as day and night. Decisions have to be made but when made in the uncertainty cannot be depended upon. You could be moving in zig-zag but you would be moving anyway. So keep moving and don't make decisions too much of a burden once you have learnt better afterwards.
