The idea, and especially its unconditional forcing down the throat, that you can run marathon faster by running it in 100m sprints. That idea is wrong as it has been shown many time in practice, yet even the slightest doubt of that idea is squashed. Scrum is basically an ideology/cult, and as typical for such it is built on a lie - it is sold to rank-and-file as performance improving whereis its real goal is improving reporting to the manager at the cost of rank-and-file's performance, the manager's convenience at observing the status even if the things are relly moving much slower as a result. It is similar to how in a religious cult people would be sold on supposedly reaching nirvana/etc. while in reality the guru/pastor/etc. would be abusing them financially/morally/physically/etc.
