 Reiss argued that it was more effective to engage with pupils' ideas about creationism, rather than to obstruct discussion with those who do not accept the scientific version of the evolution of species.In July 2009, he led a number of the UK's most senior scientists in writing to the Schools Secretary Ed Balls to complain that Ofsted's proposed new curriculum for primary schools did not mention evolution.In 2010 Reiss debated Michael Behe on the topic of Intelligent Design.
