Frontloading

In divination, "Frontloading" is when any excess information is given to a practitioner which imply details about the target and that information affects the reading. This is universally considered a bad thing, as it deteriorates the credibility of the reading (as what's given might be derived from that information and incorrect) and can even replace actual details of the reading with assumptions. It's generally suggested that you give the practitioner only the bare minimum amount of information needed to lock onto the target.
