Abstract
What is negative about negative data? Scientists
understand negative data from our training in data
analysis and statistics, where we use a positive concept of
negative data. Negative data are data that do not enable us
to reject our null hypothesis. Such data are often difficult
to publish because it is not possible to prove the null
hypothesis. Every active research scientist has a large
drawer where these data languish. In the area of
environmental biosafety, however, some scientists have
begun to use "negative data" in a second, normative way.
This normative concept of negative data has socio-political
connotations, where "negative" data has come to
connote results that GMO proponents could use to
support, and GMO opponents could use to oppose the
development of GMOs. This politicization of GMO
biosafety research is worthy of study in its own right, but
EBR is prepared to accept any kind of "negative" or
"positive" data.

| What is OpenURL? |
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
