This is one reason it's hard to trust science, they start of with a bias and confirm it, but make it look like it was objective. You'd need decades of research

This is one reason it's hard to trust science, they start of with a bias and confirm it, but make it look like it was objective. You'd need decades of research to even come near a conclusion on something like this. "suggests" is doing a lot of the heavy lifting there, but the general public, policy makers, executives, hr, etc.. will read "it's a fact", and I suspect whoever funded this knew exactly what they're doing.
