Hossenfelder criticises what has become the standard operating procedure of particle physicists, whereby they routinely predict the existence of particles that violate the Standard Model. Eventually, the postulated particles are experimentally falsified, at which time physicists move on to even more fanciful predictions.
Hossenfelder is pessimistic about the future of the field if particle physicists continue to behave in the same manner going forward. Hossenfelder also notes that in the past 50 years, only a handful of predictions have been validated, and all these were necessary elements of the Standard Model.
