“…Overall, results from 103 assessed courses designed to increase cognitive complexity each show significant IC gain, including courses run in secondary schools in Scotland, Finland and Pakistan (reviewed in Boyd-MacMillan et al, 2016;Nemr & Savage, 2019;Peracha, Savage, Khan, Ayub, & Zahr, forthcoming). This body of research, leveraging and measuring IC, has been delivered across 10 countries to address a range of extremisms (Islamist, right wing, left wing, sectarianism, national separatism, and inter-group conflicts), showing cross-cultural replication, with each course adapted to context, using a process similar to the A, B, C, D stages described above (Boyd-MacMillan et al, 2016;Liht & Savage, 2013;Nemr & Savage, 2019;Peracha et al, forthcoming;Savage & Andrews Fearon, 2021;Savage, Liht, & Khan, 2014). Of this, LWWD is the first critical thinking course designed to increase cognitive complexity to address social polarisations or extreme thinking of any kind in secondary schools in England.…”
