The political science (as opposed to real science) has dominated in the stem cell debate, especially regarding promotion of human embryonic stem cell research. In the stem cell debate, claims for human embryonic stem cell research advanced a political agenda -- legitimizing and guaranteeing federal funding for ethically contentious research. For the same political reasons, the increasingly strong evidence of actual therapeutic benefits to patients from ethically non-contentious adult stem cell research was distorted or concealed. For example, the patterns of behavior promoting public funding of human embryonic stem cell research show extreme politicization of the science involved--selective use of data, manipulation of the peer review process, demonizing colleagues who questioned the prevailing orthodoxies and appeals to a bogus scientific "consensus," among others. Those who questioned this supposed "consensus" were dismissed as scientifically ignorant and accused of playing politics with science.
