Extension of the "friction is good" family of heuristics: when facing two options, the harder one to execute is more likely to be the meaningful/right choice, because an easy option needs no real justification to pick — you'd take it regardless of whether it was correct. A hard option only gets chosen if something is genuinely pulling you toward it, so its difficulty is itself evidence of signal.
Herzberg (Wiz) illustrates this with a breakup analogy: staying in a relationship is the path of least resistance and doesn't need justification, while leaving requires a reason strong enough to overcome inertia — so the fact that leaving feels so much harder is itself what makes it trustworthy as the "true" choice. She applies the same test to career and product decisions: when one option is comfortable and the other effortful, treat the effortful one as more likely to carry the real signal.
