Manager: The only employees who should receive bonuses this year are those who were exceptionally productive over the past year. Liang is an excellent account executive, but she works in a corporate division that has failed to meet its productivity goals for the year. Thus Liang should not receive a bonus this year.
The reasoning in the manager's argument is flawed in that the argument reaches a conclusion about the performance of one member of a group merely on the basis of the performance of the group as a whole.
