Can this be confirmed or refuted?

There is so much variation confounding any study, in tasks, specifications, programmer inclination.

I use both staticly typed (rust) and dynamically typed (perl) a lot. I like rust for the big projects and perl to hold everything together-job control

That is my inclination, not a fact.

I have used many languages over the years. Static/dynamic typing is just one dimension, and not necessarily related to quality
