According to a survey conducted by a clinic located in Seoul Gangnam's Seochowon, SNSD's YoonA was chosen as the most intelligent girl group member. 273 people were asked to choose one girl group member that seemed to have an intelligence above the rest, and 148 (54.2%) of the vote went to YoonA. Runner up was KARA's Goo Hara with 23.4% of all votes, followed by After School's Kahi who earned 18.3% of the overall vote. The clinic explained, "The participants felt that girl group members who actively sing, act, and make numerous variety show appearance must be the most talented and intelligent. It takes a lot of brainpower to be able to do all three with finesse, and they most likely grew progressively smarter over time, as the human brain further develops the more you utilize it" YoonA and the rest of her SNSD members have recently made a comeback with their new album 'The Boys' and achieved an all-kill shortly after the release.
