Conventional wisdom judges that the people of the United States to have few concerns about biotechnology in comparison to people in other parts of the developed world.  According to data from a new survey, this picture is at once both accurate and misleading.  At least one other major comparative study using data from 1996-1997 published this year appeared to indicate generally more favourable attitudes in the US than in Europe.  But recent data reflect mixed opinions in the US consistent with other evidence suggesting moderate declines in US support.  While the proportions may be slightly different, the US increasingly resembles Europe in having significant amounts of opposition.
