I wonder what is the negative of having many possibilities. I sometimes find my self stagnate in some process when it comes to decision making. An the more opportunities I have the more I struggle. Are there studies, books, articles comprising this phenomenon?
The problems presented by having too many choices are defined at the personal level by Overchoice and at the organization level as Analysis Paralysis. However, they both cover the same idea, wherein too many choices overwhelm a person's decision making process as each alternative is considered.
There are several perspectives that you can take in understanding your (and others) difficulties in making decisions when there are a lot of options. You could think like a psychologist, in terms of the psychological processes involved e.g. Regret Theory. Or you could think like an economist in terms of strict assumptions about the desirability of different options and how they relate to one another e.g. Opportunity Cost. Really, there are so many different ways you could approach this that it's hard to give specific books or papers you could read.
In general, though, the key problems with making a decision when there are many options is the increased difficulty in making the "best" choice (which is often the goal) and also the fact that when one makes a decision about one option, one has to give up on the other options. When there are more options, there is more given up by making a choice.
I myself found a paper dealing with 3 studies that all together answered my personal question. It's the studies of Iyengar, S. S. und Lepper, M. (2000), which point out that having many opportunities can harm decision making and can even lead to dissatisfaction after making the decision. I actually can't say how trustworthy this studies are, since I'm not from this subject, but they correspond to my own experience.
