irrationally

Against all reason

Irrationally describes doing something without logic, reason, or good judgment.

When someone behaves irrationally, their actions don't follow from sensible thinking—they may be driven by emotion, fear, or impulse instead.

She knew she was reacting irrationally, but couldn't help herself.

The word often carries a tone of criticism or self-awareness, acknowledging that the behavior doesn't make sense even to the person doing it.
