Beginner's luck
Unexpected success by a novice
From Wikipedia, the free encyclopedia
Beginner's luck refers to the phenomenon of novices experiencing a disproportionate frequency of success or succeeding against an expert in a given activity.[1] One would expect experts to outperform novices; when the opposite happens, it is counter-intuitive, hence the need for a term to describe this phenomenon.[2] The term is most often used in reference to a first attempt in sport or gambling, but is also used in many other contexts. The term is also used when no skill whatsoever is involved, such as a first-time slot machine player winning the jackpot.
