is much more embarassing AND it is bad science.
Dr. Homer Jacobson corrected his errors about the possible origin of life in an article which he wrote and which American Scientist, The Magazine of Sigma Xi, The Scientific Research Society published in 1955
"He wrote in his retraction letter, ‘I am deeply embarrassed to have been the originator of such misstatements.’
It is not unusual for scientists to publish papers and, if they discover evidence that challenges them, to announce they were wrong. The idea that all scientific knowledge is provisional, able to be challenged and overturned, is one thing that separates matters of science from matters of faith.
So Dr. Jacobson's retraction is in ‘the noblest tradition of science,’ Rosalind Reid, editor of American Scientist, wrote in its November-December issue, which has Dr. Jacobson's letter."
