Predictile dysfunction (PD) means that you cannot get and/or maintain a prediction. In some cases the prediction becomes partly firm, but not hard enough to actually perform. In severe cases of PD, there is no movement in the prediction at all.
The media had a bad case of predictile dysfunction when projecting Hillary w to win the presidency.
To project an educated guess on someone's behavior based on a self-centric point of view.
