Are humans rational?

Sometimes yes, sometimes no, some much m,ore so than others.

I think a better question to ask may be, are they wise?

GOD bless

Most of the time, no.

Some are and some aren't.

not that I have seen

humans can be both rational and irrational by their own choosing

Not often.  Or for long.

Gotta watch that all the time.  Reality check, honest and often.

Several here often demonstrate what happens when you don't.

Partially. Not entirely. And thank heavens for that! Both for the fact that we partially are, and for the fact that we are also more than that. <3

Not often enough.

We have the capacity to be. It just isn't always turned on.
