Caution! The answer you get to a question depends very much on how you ask it - what words you use and what introductory information you give people before asking the question. With EMFs, it would appear that:

• The more you talk about the science and the possibility of a health risk (and, obviously, the more alarming you make it sound) the more people will appear to be concerned.
• Conversely, the more you put EMF in the context of other issues, the less people will seem to be concerned about it.

To understand the results of any study (and to understand the widely varying results that have been obtained) you need to know how the questions were asked.  The series of polls by IpsosMORI conducted for National Grid were designed to test the public view with as little bias as possible.
