Put a limit on it: The protective effects of scarcity heuristics when self-control is low.

Low self-control is a state in which consumers are assumed to be vulnerable to making impulsive choices that hurt long-term goals. Rather than increasing self-control, the current research exploits the tendency for heuristic-based thinking in low self-control by employing scarcity heuristics to promote consumption choices. Results indicate that consumers low in self-control especially benefited and selected more healthy choices when marketed as "scarce" (Study 1), and that a demand (vs supply) scarcity heuristic was most effective in promoting utilitarian products (Study 2) suggests low self-control involves both an enhanced reward orientation and increased tendency to conform to descriptive norms.
