The Scarcity Mindset: How Lack Affects Decisions

Being short of money or time narrows focus, which can help in the short term but hurt longer-term choices.

Researchers Sendhil Mullainathan and Eldar Shafir argued that scarcity — of money, time, or other resources — captures attention and changes how we think.

Their work helps explain why people under pressure sometimes make choices that look short-sighted from the outside.

I Tunnelling

Scarcity creates focus on immediate needs, which can make people more efficient in the moment. But it also creates “tunnelling” — neglecting things outside the immediate problem, such as long-term planning.

II Mental bandwidth

Research suggests the stress of scarcity can take up mental bandwidth, making other decisions harder. Findings from some individual studies have been debated, but the broader idea has influenced policy design.

III Implications for policy

  • — Simplify forms and application processes
  • — Use reminders and defaults
  • — Avoid complex rules that penalise small mistakes
  • — Offer flexible payment timing

IV For individuals

Building a small buffer of savings or time can reduce pressure and improve decision-making. Automating bills and savings helps reduce the number of decisions to make.
