As in all cases “science fact” is used loosely.
The Main Claim About Teacher Somatotypes
In Nonverbal Behavior in Interpersonal Relations the authors observed that:
“Teachers who are ectomorphic are usually perceived by students as anxious and less composed but perhaps intelligent. The endomorphic teacher is generally perceived by students as slow, lazy, under-prepared, and not dynamic in the classroom. The mesomorphic teacher is perceived as credible, depedable, likable, and competent but possibly tough and dominant.” Virginia P Richmond and James C McCroskey, Nonverbal Behavior in Interpersonal Relations (Boston: Pearson/A and B, 2004), 269
For those who don’t know:
- Ectomorphs are lanky body types
- Endomorphs are dad-bod types
- Mesomorphs are beefy (muscly) types
Is that a reasonable claim? What is the evidence?
Now, here’s where things might get interesting. In this social-psychology text, several paragraphs per page will be riddled with citations. But this particular paragraph cites no studies. Is this just a personal observation? Is it an impression?
I don’t know.
I think that it’s probably partly true. There is some research that shows similar stereotypes in the broader population toward the somatotypes (which, since they’re based on eye-balling, are basically observational, not genetic categories).
I did find a study from the eighties showing that one class of students rated, based on photographs, attractive teachers and female teachers higher on scales of competence, organization, and imagination.* Of course, to extend this finding further seems like a hasty generalization. But that’s the only one I could find about teacher somatotypes and it wasn’t referenced in the textbook.
One study checked for stereotypes on the three body types and differences between the sexes both in stereotype attributed and in stereotype attribution. In this particular study, ectomorphs were perceived favorably despite historically negative stereotypes.** But over all mesomorphs were still perceived most favorably except in terms of intelligence and meanness. Big muscles can make you look stupid and mean. In this particular study, there were some gender differences: female mesomorphs didn’t suffer on the perceived intelligence or kindness rating. And female endomorphs weren’t perceived as more sloppy compared to male endomorphs. These generalized stereotypes could be applied to teacher somatotypes.
It’s important to remember that none of the observations above are about stereotype accuracy. That’s a different cake to bake.
But I will make a suggestion here: If you are of a somatotype about whom certain stereotypes are made, it is important in a professional setting to put those stereotypes to rest if your workplace requires merit. If people assume you’re a stupid jerk because you lift, but your boss expects you to be kind as a part of your job, you have to break the stereotype. If you’re not in a merit based job, then those stereotypes may not matter to you. I would suspect that these stereotypes apply to all fields.
