「常識」（Common Sense） P45P
see p. B43
常識 usually represents practical wisdom, but there are other possibilities.
Digital Minds with extensive databases of past experiences, or the ability to think many steps ahead, might enjoy the same benefits.
More dramatically, this trait could represent divine guidance --after all, advice given to the player by the GM comes from a Higher Power from the character’s point of view.

■代案
Those who are good at avoiding incorrect decisions as opposed to stupid ones have 直感 (p. 56).
“Correct” isn’t automatically the same thing as “smart”!

■追加特別増強
Conscious: Not only does the GM warn you when you’re about to do something stupid . . . you can ask him to suggest what would be smart in your current situation.
He’ll roll secretly against your IQ; the better the roll, the better the advice. +50%.

■パワーアップ
常識 could be psionic:
the ability to draw upon the collective wisdom of others fits Telepathy, while the capacity to see enough of the future to know the outcome of one’s actions suits ESP.
It might represent divinely imparted wisdom instead, making it appropriate for a divine power.
Those with moral powers may receive similar guidance from their “moral compass.”
才能 adds to IQ rolls to use this ability.
