A much harder (for researchers to devise) but a lot more beneficial form of gamification is 'implicit gamification'.

Why do you have to move gamers away from their favorite Battlefield, DoTA, CSGO, LoL, Starcraft, or whatever games, in order extract value out of the huge amount of decision-making going on?

- Gamers play their favorite games.

- The decisions they make during the gameplay get translated into decisions about non-trivial aspects of scientific work. (This is the hard part).

- Those decisions lead to scientific progress.

I'd love to find out if anyone is working on this, or what is the state of the art in this area.
