Rating process retaliatory grading

[alitarraf]

Page 22, footnote 6.

It is unclear how a pre-commit and reveal scheme will avoid retaliatory grading in future task assignments.

Manager assigns worker and evaluator. If manager is also the evaluator he already knows the worker (address, reputation, past activity).

Hiding gradings with reveal and commit helps current task retaliation, i.e. oh you graded me a 1, even though you did a good job, i will grade you one.

What about future tasks with same mix of worker, manager/evaluator? Perhaps, manager would not want to assign that task to that worker again or vice versa worker not wanting to submit a task for that manager. Also this brings the question of the right or not of worker to refuse a task as not to incur a reputation penalty if they ignore manager assignment....

Just thinking out loud while am reading the document, i realise this gets into human psychology at work.
