I am a PG(170-180 IQ)23 year old student wanting to obtain a Ph.D. in Cognitive psychology or Neuroscience. Do you think that it is appropriate to place High IQ groups on my graduate school resumes/CVs? These groups certainly have permitted me to meet others with similar interests; I also communicate with them and have lively, delightful, and inflamed intellectual discussions.

is it a good idea for me to list these High IQ groups (i.e. Mensa, Intertel, 4G) in the club/group section on my resume?

The reason I ask is because my GRE scores were not great--I was hoping that my membership in these societies might compensate for that. Also, these groups really HAVE been beneficial for me socially.
I just fear coming off as pretentious, gauche, or rude.

What do you think? Thanks so much!
