▪︎Popularised by Mr Sunday Movies/ The Weekly Planet Podcast, the M.A.S.H effect is from the famous TV show M.A.S.H.
▪︎When one character would leave the show, (being set on an army base) the role would need to be refilled by somebody else. Who would have the exact opposite personality and type of character.
▪︎So for example the Doctor character, originally was a draft dodger who did not want to serve, he spent most of his time fishing rather than helping his comrades. He was replaced by a Career Surgeon who took great pride in his work.
▪︎I’m not an expert of the show M.A.S.H, so don’t @ me.
