From what I understand, the positive correlation between self-esteem and accomplishment exists up to a point on the self-esteem scale; from that point on, high(er) self-esteem seems to become counterproductive.
Can you cite a study to support that? I wouldn't normally ask, but I've never seen that claim made before.
Of course, performance and accomplishment can be difficult to measure in a meaningful and objective way.
They really aren't. There are innumerable ways to measure performance. The difficulty is in measuring self-esteem.
Many studies on self-esteem and accomplishment are done on students by measuring their accomplishment in terms of academic success that seems to be easy enough to measure.
How relevant those results are is another matter.
More recent studies have shown that the positive correlation between high self-esteem and academic performance went in the opposite direction; that is, good academic performance lead to high self-esteem. And in any case, consensus seems to be that whatever the correlation is, it's insignificant.
But I think we can all agree that a certain measure of self-assurance, self-confidence, self-esteem of however we wish to call it, is necessary to have interactions with other people that the person themselves experiences as meaningful and successful.
That's far too general a statement. I don't know what you mean by "a certain measure," or "meaningful and successful."
Then this is how it seemed to you.
No. This is your conclusion.
Then please tell me how I have it wrong. How is this:
It's no mystery that there is a positive correlation between self-esteem and achievement (in various areas, from academic, sports, to work).
...is anything less than a conclusion based on an assumption?
I consider declarations of certainty to be:
1. Rhetorical maneuvers,
or
2. Manifestation of extremely high-self-esteem,
or
3. Expression of factual certainty.
In actual communication, it is often hard to tell which is which and how to reply to a person who has made a declaration of certainty. (Do they actually know and should be trusted, or are they just boasting?)
Often, factual certainty would require nothing less than omniscience.
Arguably, people often make declarations of certainty as a rhetorical maneuver that allows them to get the upper hand in the communication or relationship, and many other times as a matter of presenting and maintaining a particular self-image in the presence of others.
Limiting declarations of certainty only to factual certainty would leave people very little to say, and with little means to get the upper hand in communication/relationships.
I said nothing of factual certainty. I was talking about studying evidence and reaching a conclusion based upon that evidence. You claimed that even this required more self-esteem than you can muster, yet you've since made a handful of claims based on far less than my claims were. Even this quoted passage above contradicts your initial claim, as it is a conclusion based on personal experience. So again I ask: Why can't you do the same with a study of religion?
