Learned industriousness
When effort itself has been rewarded, the sensation of working hard becomes less aversive and even reinforcing.
What it means
Learned industriousness is the theory that the experience of exerting high effort can acquire secondary reward value if effort has reliably been paired with reinforcement, making people more willing to work hard across tasks. Conversely, when low effort is rewarded, the sensation of effort retains or gains aversiveness, breeding general laziness. The mechanism is conditioning applied to the internal cue of mental or physical exertion, so 'industriousness' becomes a learned, partly transferable trait rather than a fixed disposition. Its nuance is that it predicts cross-domain transfer of work ethic, a stronger claim than ordinary reinforcement, and the evidence for broad transfer is mixed. It matters as a counterweight to the overjustification literature, showing conditions under which rewarding effort builds durable diligence rather than undermining it.
Examples
A child consistently praised for trying hard, not just for winning, later tackles unrelated difficult tasks with more willingness than peers rewarded only for easy successes.
A junior lawyer at a firm that rewards the grind of a hard brief, not only the win, later takes on gruelling cases that colleagues quietly avoid.
Someone who trained through the burn of long runs and got steadily faster starts to find the ache of a tough day's decorating satisfying rather than off-putting.
