On August 20, 2010, Michael Smith, Dean of Harvard's Faculty of Arts and Sciences, released a statement confirming that an internal investigation had found Hauser guilty of eight counts of scientific misconduct.
However, Harvard stated that "in cases where the government concludes scientific misconduct occurred, the federal agency makes those findings publicly available.
[3] In his resignation, Hauser stated that he had "some exciting opportunities in the private sector" involving education for high-risk teenagers, but that he might go back to academia "in the years to come.
"[20] In September 2012, after conducting a separate investigation, the Office of Research Integrity (ORI) found Hauser guilty of scientific misconduct.
[24] In April 2011 Hauser and Justin Wood (coauthor of the original paper) replicated the results of the 2007 Science study and published them—as an addendum—in the journal.
[31] However, in 2001 Hauser reported that his subsequent attempts to replicate the experiments were unsuccessful, observing no evidence for the previously claimed result.
Michael Tomasello, another well-known animal cognition researcher, claimed that some of Hauser's previous students personally told him that there "was a pattern and they had specific evidence".
[36] An article in New Scientist claimed that Harvard opened its investigation of Hauser's lab after students who had worked there made allegations of data falsification.
[37] Gerry Altmann, the editor of Cognition, subsequently posted his personal conclusion that Hauser fabricated data as part of a deception, after being given a summary of the relevant portions of Harvard's inquiry.
[38][39][40][41] Altmann noted that the conclusion of fabrication was his own conjecture, and not that of the Harvard investigation, which offered no explanation for discrepancies between the video record and the published paper.
