<p>I know that all those campuses have thousands of students, and that friendliness - like every other human characteristic - has aspects of a normal distribution curve. There will be small numbers of exceptionally friendly and unfriendly people, larger proportions of mostly friendly and mostly unfriendly people, and a huge bloc of people in the middle. Given that college students are in the peak social-life years, you’ll find the scale everywhere to be skewed towards the “friendly” end. There may be differing vibes - e.g., intellectual at Swarthmore, preppy at ConnColl, activist at Wesleyan, Southern at Clemson, etc. - but you’re not going to find any real, measurable differences in basic friendliness.</p>
