Re: As usual, hire a female CEO when the company is collapsing
Probably in some cases, but for many countries, there's not a lot of chances to put a scapegoat in power since there's an election in the way. Unlike a company, where a small group of people can name someone CEO in a couple days if they want to, if there's a general election, then you can't just decide who the winner will be. For this reason, Thatcher couldn't have been a perfect example because a lot of people voted for her, and she's likely not to have been an example at all, since picking a scapegoat during a general election would nearly always be harmful to the party. Before it comes up, the situation about Truss fits this much better but is likely also not an example. If Truss had been named without a general election because something bad had been set in motion and she was intended to take the blame, that would fit the pattern. As far as I understand it, this was not the case, she had to campaign for the position, and the problems leading to her resignation were created after her appointment, not before it.
It has been seen before, though, and it can frequently not involve gender at all. For example, if a military wants to start a coup and to have an excuse, one tactic they have used is to put in a leader who will make unpopular decisions, so they can spin the removal of that leader as their duty rather than a power grab. This is not always the case in coups, as often the military doesn't particularly care about being subtle and, if they have the power to name a leader, they may skip the scapegoat process. A related tactic is to try to convince the existing leader to make unpopular decisions rather than replacing them, which has happened more frequently.
