This drivel is a mixture of the obvious & naivety
How often is the obvious ( based on common sense and basic science ) obscured in training sessions where the naivity of the trainees allows the trainer to convince the trainees that he the trainers is telling the truth and the whole truth about the product they are being trained to install and/or service. It is not just in the training of plumbers to be boiler installers where this less than accurate training happens, car industry, domestic appliances to name but two.
