Falsifiable

A property a mechanical thesis must have — there must be observable behavior that, if it occurs, makes the claim wrong.

Full Explanation
A thesis without falsifiability is a belief, not a claim. It can be rationalized indefinitely because nothing can prove it wrong. A falsifiable thesis names the specific condition under which it expires — the mechanical wrong point. This is not a philosophical requirement — it has direct practical consequences. A falsifiable thesis tells you when to exit. An unfalsifiable one leaves exits to emotion, and emotional exits are the source of most of the damage traders do to themselves.
