A brand-new cup comes out of its packaging, a new plate is still wrapped in paper, and yet some people instinctively wash it before using it. At first glance, the behavior may seem purely practical: perhaps the person wants to remove dust, packaging residue or anything that may have accumulated during manufacturing and transport. But sometimes the ritual happens even when the object looks perfectly clean. Psychology offers another possible explanation. For some people, washing, touching, arranging or otherwise preparing a new possession may help create a feeling that the object has finally become “theirs.” This connects to the concept of psychological ownership , a feeling of possession that can exist independently of legal ownership.
