Cognitive strain, whatever its source, mobilizes System 2, which is more likely to reject the intuitive answer suggested by System 1.
System 1 is the impulsive, unconscious, eager but not very intelligent aspect of the mind.

Theory is that inducing cognitive strain diverts more mental resources to the System 2, which then tends to do a proper job at solving the test.
