Term for incentives working without conscious awareness Is there a term that captures the idea that incentives work even when people deny their choices have been swayed by them?  

For example, an individual amazon book reviewer may deny that a recent improvement in their rankings caused them to spend 10 minutes writing a review instead of 5.  They may be honest that they weren't consciously aware of the connection in a single act.  But statistically it might (by some well-controlled experiment) be evident there is likely a causative correlation, over time, over many participants.

Or changing scoring models on StackExchange might change behavior more than explainable by conscious decision.

Or a crowded store gets better sales due to social influences.

Of course perverse incentives and competing incentives (social, financial) will complicate, but I want a term to capture the concept that incentives influence choice to a degree more than the participants are aware.

So I'm not asking for argument how much or little this works, but for a well-accepted term for it.
Annoyingly, it depends what area of the research literature you happen to find yourself in. In the perception literature, the distinction lies between subliminal and supraliminal. In the memory and learning literature, the distinction lies between implicit and explicit. In dual-process decision-making theories, the distinction lies between automatic and controlled. The former terms broadly refer to "unconscious processing" while the latter terms refer to "conscious processing," but I wouldn't say unconscious/conscious is a well-defined distinction.

There is some general cross-overlap, but of these three distinctions and areas, the distinction that sees the most use in the other two areas would have to be explicit/implicit. They differ mostly in what stage of the process in the mind the researcher is interested in: perception, memory or thought. There is, to my knowledge, unfortunately no term which broadly captures all unconscious processing from input to output AND maps to the literature. 

If you want the term to map to the literature, I think you'll have to commit to one or another. If it's for a lay audience, "implicit X" is fine, where X is whatever you think best fits the intended meaning.
