The phrase "more well chosen" means something that has been selected with exceptional care and thoughtfulness. Antonyms for this phrase could include "poorly chosen," "indiscriminate," "haphazard," or "impulsive." These opposites suggest that the selection process was rushed, lacking in consideration or planning, and perhaps not very effective in achieving the intended goal. Conversely, using antonyms such as "careless," "random," or "thoughtless" to describe a decision or selection implies a lack of attention to detail, an absence of strategy, and a disregard for the overall outcome of the decision. Hence, it's crucial to carefully choose words to reflect the level of intention in the selection process.
