Like all things, the effectiveness of the above depends on a good balance i.e. distraction by simply jumping amongst topics vs. concentrated thought on any one idea at a time. They are not the same.

In Hindu/Buddhist philosophy there is a concept of "Samyama"(https://en.wikipedia.org/wiki/Samyama) and "No-Mind" (one aspect - https://thetealetter.com/japanese-tea-ceremony/mushin-discov...). What this means is that when you are reading/working/etc. on something, your mind is completely occupied with it to the exclusion of everything else. Even if that activity is of only a very short duration your mind is completely possessed by it and when it ends, your mind drops everything to do with it and moves on to the next activity to occupy itself completely. This is the basic idea behind meditation/mindfulness/etc.
