in one's right mind

Thinking quite clearly

In one's right mind describes a state of sanity, sound judgment, or rational thinking.

The phrase almost always appears in negative or conditional contexts: No one in their right mind would pay that much, I wasn't in my right mind when I agreed to this.

It questions whether a decision reflects clear thinking or temporary madness.
