Genetics opinion surveys often include information to ensure that respondents have sufficient understanding to give informed responses. The information is assumed to be neutral but may skew responses. We assessed the impact of a seemingly “neutral” information leaflet on attitudes towards genetic testing among 1,024 survey respondents, half of whom received the leaflet. The leaflet group reported higher levels of subjective understanding of genetic testing (68 percent vs. 53 percent), were more interested in genetic testing (81 percent vs. 77 percent), and held more positive attitudes towards genetics than people who did not receive the leaflet. Information leaflets may have the intended effect of increasing understanding, but may also unintentionally influence reported views on genetics. In the light of the weight given to public consultation in today's governance and regulation of human genetics, increased awareness of how even seemingly neutral information can influence public attitudes is recommended.
