Lead Science: Interactive Charts & Cognitive Tests
12 standalone tools. Some are charts you can pull and drag. The rest are tasks that measure what lead does to the brain while you do them.
Interactive Charts
01
Lead & Crime: Unified Animation
Overlapping canvas. Gasoline lead timeline vs crime wave, age marker, demo bar.
02
100-Person Population Grid
ADHD / IQ loss / poverty mode slider across a grid of 100 people.
03
ADHD Odds by Blood Lead Quintile
Braun 2006 NHANES data. Each bar is a blood lead quintile, 4.1x at top.
04
IQ Bell Curve Slider
Drag blood lead level, watch the population bell curve shift left. Color goes green to red.
05
NHANES: Lead Decline vs IQ Recovery

06
Bone Lead Remobilization: Pregnancy
How stored gasoline-era lead releases from bone during pregnancy and lactation.
07
Lead & Type 2 Diabetes Dose-Response
Bars by blood lead quartile from NHANES. Risk climbs with each quartile.
08

Cognitive Tasks
11
Tower of London
5 problems of increasing depth. Measures planning latency and over-moves, two signatures of frontal lead damage.
12
Iowa Gambling Task
100 trials, 4 decks. Measures ability to shift to advantageous decks after trial and error, a lead-sensitive decision circuit.
+
Digit Symbol Coding Test
90-second timed test. Processing speed, the cognitive domain most reliably reduced by lead exposure.
