Talent identification is not a single step but a pipeline, and selection and transfer sit at two different points within that pipeline, one narrows down candidates already in a sport, the other redirects candidates across sports.
Talent selection, narrowing within a sport: Once a group of athletes is already participating in a particular sport, coaches and scientific testing, physical measurements, fitness scores, psychological assessments, are used to filter out those with the greatest potential and move them into higher-level, more intensive training programmes. The pool of athletes does not change sport, only the level of investment placed in each one changes.
Talent transfer, redirecting across sports: Here an athlete already excelling in one sport is identified as having physical or technical qualities that would translate well into an entirely different sport where those qualities are in short supply. A well-known real pattern is athletics sprinters being recruited into bobsled push teams for their explosive short-distance speed, or a javelin thrower's shoulder power and technique being redirected into hammer throw. The athlete's sport changes, but the underlying physical talent is reused rather than rebuilt from scratch.
In short, selection filters who continues within the same sport, while transfer relocates an athlete's existing talent into a new sport that can exploit it more effectively.
