Germans consider critical feedback to be unfair if it does not include concrete recommendations on how to improve on weaknesses. They believe that people can only improve on what they understand to be suboptimal. Critial feedback, the Germans believe, should therefore be communicated clearly, avoiding any use of politically correct language.
The more objective and impersonal the critical feedback is stated, the less chance it will be taken personally. Feedback experts in Germany go as far as to view personal relationships within teams as a barrier to honest, effective feedback. They often recommend neutral third parties to facilitate particularly critical feedback discussions.
