A lot of it has to do with how optimistic and how pessimistic you are, which is related to how much control you believe you have over an outcome. Why are you going to continue to engage in a behavior when you dont believe you will see any positive results. Seligman was huge in this field. He did an experiment on learned optimism (alright, so the experiment wasnt too pleasant, but basically he shocked dogs, and some of them he allowed to jump out of the box to avoid the shock, and some of them were stuck getting shocked no matter what they did, and then they were all put into another box and shocked again. This time, even though there was a clear escape, the dogs who had learned that they couldnt do anything, most of them just sat there being shocked). People aren't very different. They learn through the environment and experiences that there's nothing they can do, and they get stuck with that. So even when there's something they can do, they dont even try.
depends on the situation... it may be easier to just give up then waste energy fighting. it may be a lost cause so why even bother to in the first place. it may be because it takes 2 sides to make things work (if in a relationship situation!) it maybe because there is enough proof(meaning facts) to put your foot down & say "enough is enough!"
there are any number of reasons to why...you need to be a little more specific as to what the deal is for something more concrete!
Many people simply just don't believe that they have the strength to persist with something so they give up. Others are afraid of the possible negative effect extra stress will have on them. Still others just have no motivation or just don't care enough to fight their battles. Low self esteem can play in to this situation pretty well too.
Because they have less hopes ,they are not that strong to stand again and fight whatever comes in their way and then give up.Well also when you loose a lot of times,you tend to give up.I personally try not to give up whatever is going in my life,and being positive is very important and that what most people don't do.
I think mainly out of frustration. If you see a lot of negatives and not so many positives, sometimes giving up seems like the easier route to take. It is sometimes, mind you, but it solves nothing. So in the end, they still don't have the desired effect.
It's a crummy, vicious cycle.
because if you dont succeed, its best to act as though you never tried.
Laziness and self doubt.
