"Emma Briant, a propaganda specialist at the University of Sheffield, wrote about SCL Group in her 2015 book, Propaganda and Counter-Terrorism: Strategies for Global Change.

It has specialised, at the highest level – for Nato, the MoD, the US state department and others – in changing the behaviour of large groups. It models mass populations and then it changes their beliefs."
