The REC have named this pre judgement as “Halo or Horns” effect. Quite simply the “Halo Effect” can be understood as the tendency to make a decision based on a favourable preference, whilst the “Horns Effect” describes an adverse personal bias.
The Halo and Horns Effect is all about prejudice and assumption, pre judging and arriving at conclusions without considering the necessary facts and that’s when you are in danger of rejecting the right candidate based on the wrong judgement.
