Since I can't provide information on events or developments that occurred after that date, I can't pinpoint specific delusions that may have arisen or gained momentum after 2023.
However, it is worth noting that delusions can take various forms and can emerge in different contexts, including political, social, or health-related. Some delusions that have gained traction in the past include conspiracy theories, pseudoscientific claims, and unfounded beliefs about certain groups or individuals.
Conspiracy theories, in particular, have become more prevalent and amplified through social media and the internet. They often involve the belief that powerful groups or secret organizations are controlling world events for malevolent purposes. In some cases, these conspiracy theories can lead to real-world consequences and impact public health or social cohesion.
It is crucial to approach such delusions with a critical and evidence-based mindset, encouraging open dialogue, and promoting media literacy to combat the spread of misinformation. Engaging in respectful discussions based on facts and evidence is essential to address and challenge unfounded beliefs in today's world.
