Experimental studies have replication crisis, but the studies on this topic are not experimental studies. They are based on survey data and statistical analysis. They do have their challenges, but have nothing to do with the replication crisis.

What makes you say that? You have heard of the replication crisis - don’t you think that the researchers in that very field have heard of the replication crisis?
