Sinistrisme

Albert Thibaudet, who developed the idea of sinistrisme.

Sinistrisme (French: [sinistʁism]) is a neologism invented by political scientist Albert Thibaudet in Les idées politiques de la France (1932) to explain the evolution and recombination of party systems, particularly in France, without substantial changes occurring to party ideology.

Thibaudet saw that, over time, issues that previously had not been politicised would emerge, drawing public concern and stimulating demand for political action. A new political movement would form to champion the new concerns, sending repercussions throughout the existing political system. The old party of the left would be split, with some accepting the new issues as legitimate, agreeing to cooperate with the newcomers and adapting their ideology accordingly. Others on the existing left would double down on their existing ideas, refusing change: without changing their ideas, they would end up pushed de facto one space to the right, and end up as the new centre.

Meanwhile, the old party of the centre would be pushed to the centre-right, and so on. As for the very far right, over time the issues of social conservation that motivated them would gradually lose their appeal, and as old issues died off, space would be freed up for the old right to become the new far right.
