Credibility

A threat or a promise counts only if carrying it out would still suit the person making it once the moment arrives.

Often misread asJudging a threat by how severe it is or how firmly it is stated, rather than by what the threatener would want at the moment of carrying it out.

How to see it

A threat is only worth making if you would carry it out

Threats and promises change behaviour only if the other side believes you would follow through. A threat that would hurt you more than staying quiet will be ignored by anyone who thinks it through, no matter how loudly it is made.

The checkSeverity is beside the point; the only question is whether you would still prefer to do it once you were standing there.
