Word for arguing X is a problem, while simultaneously causing X

Question

It feels like there should be a word to describe, for example, politicians who proclaim government doesn’t work, then act to ensure that’s true.

I know there’s a political read in this example, that’s not what I’m actually interested in.

What do you call this behavior, where a person is the cause of, or a part of the problem they themselves are proclaiming is a problem? (And therefore a solution they propose should be applied to remedy the situation)

Hypocrite describes part of this, but it feels like there should be a more all-encompassing word or phrase to explain this kind of bad-faith argumentation.

Answer 1

This is called a self-fulfilling prophecy. Wikipedia describes it as

A self-fulfilling prophecy is the psychological phenomenon of someone "predicting" or expecting something, and this "prediction" or expectation coming true simply because the person believes or anticipates it will and the person's resulting behaviors align to fulfill the belief

Answer 2

Disingenuous describes this type of behaviour.

lacking in frankness, candour, or sincerity; falsely or hypocritically ingenuous; insincere

Example: Complaining about government debt whilst lowering taxes is disingenuous

Less formally, pouring fuel on the fire describes the action, but not the hypocrisy.

Answer 3

I think you might be looking for Spin.

In public relations and politics, spin is a form of propaganda, achieved through knowingly providing a biased interpretation of an event or campaigning to influence public opinion about some organization or public figure. While traditional public relations and advertising may manage their presentation of facts, spin often implies the use of disingenuous, deceptive, and manipulative tactics.
