This is not pyschology's replication crisis. Every field has replication problems, psychology is just one of the only fields taking it seriously.
I don't hear about rampant replication problems in chemistry/physics. https://en.wikipedia.org/wiki/Replication_crisis

There is a replication crisis in many fields. Not every field.
The difference between a scientist and an engineer is that the scientist answers the question "if I do X, what will happen?", and the engineer answers the question "what do I do in order to get Y to happen?". But if there are no engineers working off of the results, the scientist is free to say anything.
Sadly, as pointed out elsewhere in the subthread, this is a sufficient but not a necessary condition. Medicine has plenty of well-defined goals, but it doesn't know how to meet them. The cheap wisdom there is: if you want something badly enough, there will always be someone willing to sell it to you, whether or not they actually have it.

Sadly medicine has a replication crisis. I don't think chemistry or physics does.
The history of logic is a completely uninterrupted episode of crisis in replication, where the creative genius of intuition is targeted for termination as we insist upon rigorous definitions and disciplined mechanistic proof as the official workhorses while only regarding the art of surreal hypothesis divination and strongarmed notational analogies as just temporarily embarrassing stopgaps until we can tease out the procedure for automating the prodigies while managing the resultant verbosity of minutely incremental 'drudgery' through the factorization of symmetry/redundancy and begin the descent into madness of hierarchies of meta proof and possibilities of hypercomputation.
Maybe this is out of envy against the more naturally gifted such as Ramanujan, or rather out of desire to retire to the beach someday without neglecting one's responsibility in the search for ultimate knowledge, but more likely just the practicality of desiring an objective reality check when the deepest dives into the abyss of specialization and abstraction render oneself completely lonely and isolated from the checks and balances of haphazard social consensus in peer review or even the _physical_ universe's fairly arbitrary and low-precision demands in constraining and verifying empirical modeling/prediction that more casual disciplines such as sociology or physics typically set as the highest caliber of evidence.
