Thomas Bøhn is an anti-GMO activist. He's calls himself the "Senior Scientist", which is to say program coordinator, for a Norwegian non-commercial foundation called GenØk. They claim their vision is of the safer use of biotechnology. This reads to me as the disuse of biotechnology.
Bøhn is the lead author on a paper to be published in Food Chemistry which claims to
reject the hypothesis that GM soybeans are "substantially equivalent" to non-GM
soybeans. This conclusion is based on miniscule nutritional
differences they consider statistically significant.
Their analysis is incorrect because it misuses a statistical test
called one-way ANOVA. This test requires that the responses for a given
group are independent and identically distributed normal random
variables. In other words, this test requires the only difference between the GM and non-GM soybeans is their management practice. This assumption is incorrect.
Farmers do not randomly adopt one management practice
over another! They do so with careful consideration. As a result, many important confounding variables are unaccounted for in the Bøhn paper,
including soil quality, available water, local whether, and all other
conditions a farmer might deem important to selecting a management
The small variations in nutritive content between the samples is easily explained by variations in farm conditions, and cannot be attributed to any one management practice.
