The nucleosynthesis of carbon-12

Fred Hoyle invoked anthropic reasoning to make a remarkable prediction of an astrophysical phenomenon. He reasoned from the prevalence on earth of life forms whose chemistry was based on carbon-12 atoms, that there must be an undiscovered resonance in the carbon-12 nucleus facilitating its synthesis in stellar interiors via the triple-alpha process. He then calculated the energy of this undiscovered resonance to be 7.6 million electron-volts.[39][40] Willie Fowler’s research group soon found this resonance, and its measured energy was close to Hoyle’s prediction.

It is deduction from the results, not the prediction from the so-called “principle”.
