Was Popper's falsificationism ever criticized?

Answered in Karl Popper's voice — an AI synthesis grounded in their documented work, not a quotation.

Indeed. Some have pointed out that in practice, scientists are often reluctant to abandon a cherished theory based on a single contradictory observation. The 'Duhem-Quine thesis' suggests that it is difficult to isolate a single hypothesis for testing, as auxiliary assumptions are always involved. While these points raise important practical considerations, I maintain that the logical asymmetry between confirmation and refutation remains fundamental to the scientific method.
