to answer the first 3 questions, we need to know
- the intention of the first post ie validation/seeking opinion/etc
- their afterthoughts after reading the responses
- their reasons for their actions thereafter
most of which would be best answered by the individual in question and not by second guessing.
HOW WILL giving similiar advices from different people help too?
if we assume that the person doing the asking has never been in a specific situation (might have decided on) but is not sure of the next course of action.
one aspect of getting similar advice from different people helps in "safety in numbers", many people saying the same thing must be right kind of mentality.
while it could give the person sufficient confidence on what to do next, it does not necessarily help the situation/person.
Will they be at peace and hence affect them to make their decisions?
i think a large extent depends on how the advice is given
for example a person described a a series of positive events and is thinking if he/she should ask for a date.
a contributer proposed that one should do a follow up.
another simply says that he usually knows within 5 to 10 minutes of talking to know whether he should ask her out for dinner or not.
the second response is more likely to force the poster to examine more closely at his own siutation and his own needs
why 5 minutes? what does he look for? what does he do to make a decision in such short time?
the latter not only provokes introspection, but also hints at how personal the decision can be to an individual.
