Thinking it over tends to improve how people judge your character, mainly if they disagree
In three studies with 896 American adults, a stranger described as deliberating before taking a political position was rated higher in moral character than one described as answering without deliberating, but the gain showed up among participants who disagreed with the position. Among participants who already agreed, deliberating made no measurable difference, because the same pause reads as thoughtfulness and as doubt at once, and in the two studies that measured it, the doubt only counted against a stranger the participant already thought was right. Moral character was the only outcome variable, and the third study's central test missed significance.
