Most people I know are from attending school or at work.

Were you two in the same school?

Either way, I think your problem is still this. Let me repeat one more time:

"人们经常被这样一个事搞糊涂，从一个错误的原因或错误的逻辑得到一个并非永远错误的结论，而该结论偶然的正确发生反过头来令我们更加相信开始的错误原因或错误逻辑。”

This theory might be derived from your classmate's work. :)
