As far as I know, we have the following patterns with the verb make:
Make somebody do something (make somebody feel happy)
Make somebody/something + adj (make somebody happy)
Now, I can't figure out why the following sentences are correct as well.
Social networking sites make people be more truthful about their lives.**
I think the following is correct but the above one wrong:
Social networking sites make people more truthful about their lives.
Am I right? Or are both sentences correct, and why?
