Why don't more physicists subscribe to pilot wave theory?
This is the bottom line:<p>&quot;It&#x27;s been demonstrated experimentally that you can&#x27;t have a local, deterministic, real, definite theory (i.e. that would lead to demonstrably false conclusions). People intuitively expect all of those things to be true, but we can prove that it isn&#x27;t the case. The various interpretations all try to give up one of &quot;local&quot;, real&quot;, &quot;definite&quot;, or &quot;deterministic&quot; in order to preserve the others, thus preserving at least a modicum of their intuition.<p>The pilot wave idea gives up on locality&quot;<p>And I will add:<p>Multiple worlds gives up on definiteness.<p>&quot;Zero worlds&quot; (my personal favorite) gives up on realism.<p>And, of course Copenhagen gives up on determinism.<p>Take your pick.  Or go with decoherence, which kind of lets you turn a knob to give up a little bit of all four and dial in whatever setting you like.
