Replication is over-emphasised. Attempts to organise mass replications have struggled with basic problems like papers making numerous claims (which one do you replicate?), the question of whether you try to replicate the original methodology exactly or whether you try to answer the same question as the original paper (matters in cases where the methodology was bad), many papers making obvious low value findings (e.g. poor children do worse at school) and so on.

But the biggest problem is actually that large swathes of 'scientists' don't do experiments at all. You can't even replicate such papers because they exist purely in the realm of the theoretical. The theory often isn't even properly written down! They will tell you that the paper is just a summary of the real model, which is (at best) found in a giant pile of C or R on some github repo that contains a single commit. Try to replicate their model from the paper, there isn't enough detail to do so. Try to replicate from the code, all you're doing is pointlessly rewriting code that already exists (proves nothing). Try to re-derive their methodology from the original question and if you can't, they'll just reject your paper as illegitimate criticism and say it wasn't a real replication.

Having reviewed quite a lot of scientific papers in the past six years or so, the ones that were really problematic couldn't have been fixed with incentivized replication.
