Vague generalities

I like vague generalities, precisely because they're vague. When using vague generalities, it's a lot harder for someone to correct you, unlike precise generalities. For example:

Precise generality: 99 percent of college students drink at some point in college.
Vague generality: A lot of college students drink at some point in college.

Because I've provided a precise amount of college students that drink, someone could look up the statistics and point out that my information is plain wrong. But if they look at my vague generality and check the statistics, how do they compare the two? even if the percentage is low (Which it isn't) it will still be a large number of people because the college student demographic is so high. So it could still qualify as "a lot" of students. Throwing around vague generalities gives me a lot of lee way to be proven right. On the other hand, if I'm speaking in precise generalities, my claim is much more likely to be disputed because it's much more specific information. My avenues of being correct are much smaller than if I were to be speaking in vague, sweeping generalizations.
