Georgia is McCartor's flagship proof of concept, and it's an unlikely one [1] — Drew McCartor "In 2018, 41% of Georgian children exceeded the WHO lead threshold. The source: lead-based pigments added to spices for vivid color. After P…" 18:00 . In 2018, a nationally representative survey conducted with UNICEF found that 41% of Georgian children had blood-lead levels exceeding the WHO intervention threshold — a number that shocked the government and created political will for action. Pure Earth was brought in to identify the exposure source, and the culprit turned out to be hidden in plain sight: spices. Vendors were adding lead-based pigments to products like paprika and turmeric to make them more vivid — those brilliant oranges and reds that signal freshness and quality to buyers. The government tightened its regulations, improved enforcement capacity, and the results were swift and dramatic. In the hardest-hit regions, lead levels dropped by 75% [2] — Drew McCartor "Georgia lead levels down 75%: After Pure Earth helped Georgia identify lead-contaminated spices and tighten regulations, lead levels in the…" 18:38 . McCartor notes that the Georgian government now owns the agenda — the international organisations have stepped back, and the country is protecting its next generation on its own terms. He uses Georgia to show that the model isn't theoretical. Then he names other countries at various stages: the Philippines got their first large-scale survey. Ghana identified its sources. Mexico reduced lead-based ceramic glazes. The pipeline of progress is real.

In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
Tiny habit users stick to the FULL habit more

Behavioral activation rivals CBT for depression
A study found that simply scheduling enjoyable activities was as effective as standard cognitive behavioral therapy for depression, leading to its own therapy called behavioral activation.
Worry time: batch all worries to 5 PM
The 'worry time' technique — deferring all worries to a designated time of day — helps people realize they have more control over worry than they thought and reveals it is less useful than it feels.
Sleeping faster by trying to stay awake
A study found that participants told to try to stay awake while in bed fell asleep faster than participants told to try to sleep — illustrating the paradox of direct effort.
