Persian scholar Ibn al-Haytham (‘Alhazen’) has rightly been credited with many advances in optics and vision science, but recent spurious claims that he is the ‘founder of psychophysics’ rest upon unsupported assertions, a conflation of psychophysics with the wider discipline of psychology, and semantic arguments over what it is to ‘found’ a school of thought.
