How We Measured the Mind
by James Johnson

Dedication

For the kids they called slow.
For the ones who never fit the test.
For the ones who figured it out their own way.

You were never the problem.
The system was.

ACKNOWLEDGEMENTS


THANKS TO THE rebels who questioned the score.
The teachers who saw beyond the chart.
The scientists who admitted they got it wrong.
And the thinkers who never stopped thinking, even when the numbers told them to quit.
