I see that some people commit to a "safe" narrative that overrides their willingness to look at technical documentation. In the case of cloud seeding, it is a scientifically documented weather modification technique, people often dismiss concerns about it as "conspiracy" or "just water vapor" because that feels more stable than acknowledging human intervention in the atmosphere.

They are choosing a rehearsed response to protect themselves from the reality that human beings are actively tinkering with the sky.
