HN is opened subconsciously while working whenever I encounter a difficult problem. Focusing is pretty easy when the road is straightforward, but the second I run into a challenge my brain tries to escape.

Not sure what that means biologically/evolutionarily.

It means we short circuited the reward wiring in our brains with too much 'informational sugar'. We get obesity and type-2 diabetes because of refined sugar and high-fructose corn syrup. These things were never part of our diet in evolutionary time scales. Same thing with content. Our brains are getting trained to consume low effort high dopamine content so our scales for gauging difficulty vs reward of tasks are all out of whack.
