Update your beliefs.

Quantitative market research that tests beliefs, updates the odds, and shows what the evidence can actually support.

Damiana Data is a personal research project. It takes questions about markets, tests them against data, and publishes what the evidence supports, including when the answer is “we don’t know” or “it didn’t work.”

The name comes from damiana, a plant. The mark is a stoma, the pore a leaf opens only as far as conditions allow. Here it opens only as far as the evidence does.

The underlying research runs in a private research system. Each piece names its sources and the fingerprints of the files it was built from.

New pieces are posted on Instagram at @damianadata.
