The numbers McCartor presents are so large they risk sliding past the audience without landing — so he names every comparator explicitly. In 2023, lead claimed more lives than all active wars combined, all natural disasters, all road accidents, HIV, and malaria — not any one of those, but all of them added together [1] — Drew McCartor "In 2023, lead poisoning killed more people than all active wars, natural disasters, road accidents, HIV, and malaria combined. Most people …" 09:00 . Beyond its impact on cognition, he explains, lead is a cardiovascular killer: it drives heart attacks and strokes at a scale that most of the world has no framework to comprehend. The cause of death is rarely logged as 'lead poisoning' on a death certificate, which helps explain why the crisis stays invisible. McCartor's delivery is measured and deliberate — he is not trying to shock for shock's sake, but to dismantle the comfortable assumption that lead is an old problem, already handled, already solved.

In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
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.
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.
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.
Spencer Greenberg reduced his severe social anxiety dramatically in roughly 6 months through a structured exposure therapy hierarchy, culminating in asking strangers for hugs.
