My dad (late 70s) has gone full gangster conspiracy theorist. His long list of increasingly radical beliefs include:
Chemtrails control us
WHO created the pandemic
The EU is evil.
Big pharma is poisoning us (he has given up all his life saving meds)
Vaccinations are a control mechanism
Bill Gates is responsible for the weather
The Democrats wanted world war
Gaza is not real - it's all made up to persecute the Jews
The list goes on. My worry is that this radicalisation is putting his health at risk, so I would like to really understand the psychology to approach this with as much evidence as possible.
Sources are sketchy online (specifically relating to how and why older people become radicalised) - wondering if anybody has any research based insights into this.
