It is considered a serious problem by many, being a key part of the whole replication crisis. The idea that studies need to be preregistered is slowly gaining ground I feel.
It seems to me, not serious enough for decisive action apparently. Progress is slow on that front. "Knowing" and "doing" are different. Most people who smoke or eat badly are aware that it's a (serious) problem, but it does not necessarily lead to action. So that people "are aware" of something doesn't tell the whole story.
