Engineers Lesss Likely to Succumb to Contagious Yawning

It has always been suspected that yawning was contagious, but now it seems that this is truer for people who have high levels of social empathy.

The study by the University of Leeds concluded that psychology students were much more likely to succumb to yawning in response to other people yawning than engineering students, because they were intrinsically more empathic.

I'm not so sure about this. I work as an engineer and frequently sit in meeting where everybody is yawning.....

I wonder if any research has been done regarding empathic drinking...When I was a student this was a common phenomenon with engineering students.
