This thread about INT and WIS got me thinking a little about the disparate gap between what is considered a "high" stat, and what is considered a "low" stat. This is especially true when it comes to representing intelligence, wisdom and charisma.
Let's assume the "average" attribute score is 10-11. With a score of 10 or 11, there are no bonuses or penalties -- the person is considered to have average ability.
Now, with an attribute score of 8, we see a penalty of -1. With an attribute score of 13, we see a bonus of +1. In a balanced "normal"/gaussian distribution, scores of 8-13 would be within a standard deviation, and would be representative of the general "normal" population.
Why is it, then, that when someone has even a mild "8" attribute, we expect people to RP exaggerated handicaps? It's not as if we treat someone with a "13" attribute as equally special...?
As an example, it seems as if people expect someone with a "8" intelligence to barely be able to speak in whole sentences, or a person with a "8" charisma to be chronically farting and picking their nose in public, when, on the other end of the spectrum, we don't really treat someone as noticeably intellectual or charismatic until they reach 15 or so.
Compare that to someone with a "8" strength, who can still carry reasonable loads and isn't terribly much less capable of a fighter than someone with a "13" strength. In day-to-day applications, the difference between a 8 and 13 STR would go largely unnoticed. Most everyone you pass on the street is in this range, and you'd hardly be thinking any of them looked particularly "weak" or "strong".
Granted, our characters are expected to be "above" the mean average when it comes to overall cumulative stats, but that shouldn't impact general public perception of ability.
Thoughts?
