Leveraging Performance Appraisal bias for better marks in UPSC CSE Mains

Every evaluator / performance appraiser who is not trained well or is tired or bored of evaluating / appraising is a victim of the following four bias –

1) Primacy bias – The first impression affects the way the evaluator perceives the rest of your answer

2) Recency bias – The event occurring (conclusions) before the evaluator gives the marks determines the marks the candidate will get

3) Spill over bias – If the first answer is outstanding, the evaluator tends to perceive the candidate to be an excellent candidate, and hence the positiveness has a spill over effect on the rest of your answers

4) Centralising tendency bias- The evaluator who is bored of correcting or who hasn’t read your answer well or doesn’t understand your answer well will tend to give you a central score i.e. close to the average

How to use them to your advantage –

In Essay – Leverage the primacy and recency bias by writing excellent introduction and conclusion. Further, try writing Section A first so that the positives of it spills over to your second essay.
In GS and Optional – Leverage the Centralising tendency bias by attempting all the question with whatever little knowledge you have. Use the primacy bias to start your answer to the point and drift away from the question in case you have run out of points or you don’t know what else to write.

All the best!
