[ASTRONOMY] Do we keep finding tidally-locked exoplanets because being tidally locked is the more common state for planets, or because such planets are easier to detect?

Tidal locking is more likely the closer a planet is to its host star, and the exoplanets that are easiest to detect are those that are close to their host stars.  For the transit method of detecting exoplanets, the closer the planet to the host star, the more light it blocks (so it's easier to spot) and the shorter the orbital period (so it's easier to confirm).  With radial velocity measurements, which depend on how much the orbiting planet(s) tug on their host star, the closer the exoplanets to the host, the greater the effect, and thus the easier to detect.
