The mini-me syndrome refers to the phenomenon that - for instance - human resources managers and executives often tend to choose employees and successors who are perceived as similar to themselves. (The mini-me syndrome is also discussed in parent-child relationships.) This similarity can be defined in terms of age, gender, ethnicity, career path or life style. The resulting discrimination is based on a bias people making HR decisions are often not aware of (via). There is no professional recruitment process without bias awareness.
