Explanation:

The availability bias can explain why managers doing performance appraisals give more weight to recent employee behaviors than to behaviors of 6 or 9 months earlier.  Availability bias is the tendency for individuals to judge or concluded on a case based on the ease at which that case, a name or individual occurred to your mind. Hence, the manager rated the new employee better because he first came to his mind considering that he/she is a new addition to the workforce compared to the older staff members. For example, after seeing snakes in the toilet of a plane repeatedly you begin to think that it is a occurrence and you refuse to use the toilet of a plane during flights for fear that there may be snakes in them.
