No, it doesn’t. The ambiguity rises from the fact that it’s not that repeatable. There are many experiments that don’t find this phenomenon to exist when they test it. Then there’s some that do. That’s the problem.
My memory is that the majority of them find that it doesn’t exist and that a small minority find that it does.



It was advice I have myself in college… Don’t focus on getting good grades, focus on learning. Judge your success on how much you learned.
The only time my grades actually mattered was interviewing for jobs right out of college. After that, every other job is based on your previous job and non no one ever asked again.
I’m in engineering and it this doesn’t necessarily translate to other fields. But I’m currently the cto for a mid sized tech company.
