Lead In Paint Is A Huge Neglected Global Problem
- Lead exposure remains a major global public health problem with huge economic consequences.
- Lucia explains one in three children worldwide have some level of lead poisoning and some countries lose ~8% of GDP from it, yet prevention (banning lead paint) is relatively simple.

- Many people choose charitable actions that feel good or signal status rather than those that maximize impact.
- Lucia contrasts feeling-good local acts with deliberate analysis to prioritize high-impact interventions like policy change or cost-effective charities.

- Self-signalling explains many 'feel good' behaviours like hygiene and productivity theatre.
- The hosts give examples: over-washing sheets and producing neat but useless notes are less about utility and more about feeling or projecting competence.
