Choosy significance is rather difficult to understand. It refers to someone who is exceptionally selective and disapproving. A persnickety individual typically pay strict attention to detail and does not settle for less when it comes to criteria and excellence. Their attention to detail can be seen as admirable, but it can also lead to excessive criticism and superfluous dissatisfaction. Being persnickety is often related to meticulous attention to detail but can also be seen as a type of pedantry.
