True.

That said... the term "underlying nature" may be part of that backwardsness.

We intuitively model human behavior as underlying beliefs and stuff leading to a rationale, leading to behavior. But really, it's often the other way.

There is an underlying behavior, behavioral pattern or whatnot. The rationale, beliefs and suchlike are overlying.

We do know these things exist, but tend to think of them as pathlogies and abhorations... like motivated reasoning. But, conscious reasoning following an intuitively reached conclusion is probably the standard model for human reasoning.
