I kinda figure that as animals, we need to do what keeps us alive. A good situation is nice and will provide benefit in the long term. However, a bad situation can present immediate danger to life or limb, therefore it's important that we learn quickly to avoid it.
This example is gross, but it does show my point. If you vomit, regardless of the reason for the emesis, whatever you taste as you puke will permanently cause nausea when you smell or taste it in the future. The theory goes that we are probably barfing due to what we ate, so it is VERY important that we learn to not eat it in the future.
My theory is that we are simply programmed to have stronger reactions to negative stimuli as their damaging effect can be a bit more far reaching than possitive stimuli.
