Gimme Some Truth

I'd be lying if I said I found this study fascinating and the scientific community is united in that fact.

Students stretch truth on teacher evaluations, UNI professor's study finds

A third of students surveyed admitted to stretching the truth on anonymous teacher evaluations.

A majority of students said they know other students who have done the same.

Twenty percent of participants admitted they had lied on the comments section of the evaluations.

I can't help but wonder if this study was done anonymously and if so, how the professors know they're not being lied to now?
