IF YOU FEEL YOU’VE LOST AT LIFE…:

Why the chemtrail conspiracy theory lingers and grows – and why Tucker Carlson is talking about it (Calum Lister Matheson, 11/14/25, The Conversation)

According to psychologist Rob Brotherton, conspiracy theories have a classic “heads I win, tails you lose” structure. Conspiracy theorists say that chemtrails are part of a nefarious government plot, but its existence has been covered up by the same villains. If there was any evidence that weather modification was actually happening, that would support the theory, but any evidence denying chemtrails also supports the theory – specifically, the part that alleges a cover-up.

People who subscribe to the conspiracy theory consider anyone who confirms it to be a brave whistleblower and anyone who denies it to be foolish, evil or paid off. Therefore, no amount of information could even hypothetically disprove it for true believers. This denial makes the theory nonfalsifiable, meaning it’s impossible to disprove. By contrast, good theories are not false, but they must also be constructed in such a way that if they were false, evidence could show that.

Nonfalsifiable theories are inherently suspect because they exist in a closed loop of self-confirmation. In practice, theories are not usually declared “false” based on a single test but are taken more or less seriously based on the preponderance of good evidence and scientific consensus. This approach is important because conspiracy theories and disinformation often claim to falsify mainstream theories, or at least exploit a poor understanding of what certainty means in scientific methods.

Like most conspiracy theories, the chemtrail story tends not to meet the criteria of parsimony, also known as Occam’s razor, which suggests that the more suppositions a theory requires to be true, the less likely it actually is. While not perfect, this concept can be an important way to think about probability when it comes to conspiracy theories. Is it more likely that the government is covering up a massive weather program, mind-control program or both that involve thousands or millions of silent, complicit agents, from the local weather reporter to the Joint Chiefs of Staff, or that we’re seeing ice crystals from plane engines?

…it’s more comforting to believe you’ve been conspired against than to accept personal responsibility.
