vapid/vacuous

Is a person "vapid" or "vacuous"? Well, that all depends. I guess if you're a cannibal then, yes, that individual can be vapid.

Technically, the word means "without flavor or very bland." Food can be vapid. Conversation can be vapid. If it's not very in-depth, I guess a book can be vapid, too. A person? Let's not even go there.

If your intended meaning is that the person is intellectually challenged, or, better yet, just plain stupid, then you want to go with "vacuous." Things generally are vapid, and people are vacuous.

Now that I think about it, I know quite a few vacuous people.

I have to change my circle of influence.
