I'm very skeptical of scientists who destroy experiment data. Storage space is less of a problem every year, and it is a huge comfort that you can ask a researcher for the data they collected.

In this case she was actively destroying data after finding contradictory evidence. It is hard for me to conceive of a situation where that would be appropriate, especially where there other researchers cannot duplicate her experiments.

I completely agree. At what point is it EVER ok to destroy scientific research data? I understand that in some fields the experiment products can be MASSIVE and storing that raw data might be impossible or impractical (i.e. baseband radio data that might be terabytes per hour). In this case it's maybe a few tens of gigabytes of data if the files were properly digitized? At most a few tens of terabytes, which is chump change!

I agree with the author's comments that this seems like retroactive action taken when it came to light that there might be other factors involved (the other lesion, etc). Or to prevent re-interpretation of her findings that might point out things she ignored/hid.
