Such pieces usually present, often in forceful language, the author＇s belief that transgenic technology is beneficial, without negative effects, and is only opposed by dark forces, that often also are portrayed as ＂unscientific＂, enemies of progress or wor- risome, misinformed persons. Without dwelling too much on causes, or arguing about mixing facts with beliefs and interpretation, let me just remind the read- ers that overconfidence in one＇s field can result in the infamous ＂ infallibility syndrome＂, when the affected starts to have illusions about the range of things s/he understands, and typically better than anyone else. This usually afflicts otherwise successful senior academics. The problem, as the eminent ecologist, Sir John Lawton observed （Lawton, 1992）, is that persons suffering from the infallibility syndrome are not aware of it. The ecological effects of transgenic crops have long been an area with more than its usual share of contributions by such afflicted persons. However, ecology is a field that has a well-articulated toolkit, and conceptual frameworks that can be usefully employed to understand the environmental effects of transgenic crops. These tools need to be learned, just as in any other field, before one can meaningfully con- tribute to discussing or solving its pertinent problems.
