Backed by the Audacious Project, Pure Earth is deploying its three-step model in over 20 countries home to 500 million children. Over the next 8 years, the program aims to improve not just those kids' health and intelligence — but every generation that follows.

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.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
