> The report concluded that the fudging of results under Tessier-Lavigne’s purview “spanned labs at three separate institutions.” It identified a culture where Tessier-Lavigne “tended to reward the ‘winners’ (that is, postdocs who could generate favorable results) and marginalize or diminish the ‘losers’ (that is, postdocs who were unable or struggled to generate such data).”
> There was no evidence that Tessier-Lavigne himself manipulated data in the papers reviewed, the report concluded, nor that he knew about manipulation at the time, but he “has not been able to provide an adequate explanation” for why he did not correct the scientific record when presented the opportunity on multiple occasions. In his statement, Tessier-Lavigne wrote that he was “gratified that the Panel concluded I did not engage in any fraud or falsification of scientific data.”
In other words, he created a culture in which fraud could be expected, and he didn't address it properly when it was brought to his attention. I'm not giving him any gold stars for ethics. But as far as I know, he didn't personally falsify research.
