This is apparently the world’s longest joke (maybe because of the format?) http://longestjokeintheworld.com/ but how true are the conclusions at the end?
Bits and pieces of all three types seem to apply to me, so I suspect we have a bit of Forer effect going on here…
I only read the whole thing because I had nothing else to do at 3:00 am, could not sleep. Normally I would have skipped to the punch line.
That is indeed one of the problems: whether or not people read to the end depends not only on their personality, but also on circumstances.
