Comment lefties vs lefties (Score 5, Interesting) 131
It's pretty obvious what the left-handed advantage is when you have sports where lefties can compete directly against other lefties. In my own sport of fencing, lefties enjoy disproportionate success (close to 50% of world champions are left handed), and they are widely regarded as difficult opponents. But pit two lefties against each other and you will often get a shitshow of awkward, hesitant, and poorly-executed techniques, despite the fact that the tactical situation is identical to right-vs-right, the most common and well-understood scenario in the sport.
The reason is easy to understand - everyone, regardless of handedness, gets 85% of their practice against right-handers. Lefties are, quite simply, weird, even to other lefties. We don't get enough practice with them, we don't get the time to develop highly-trained "favourite moves" with them, and we don't ever enjoy the comfort and ease of familiarity. Our cognitive load is increased, and our reaction time is slower.
Unless you're lucky enough to have a left-handed coach, or a disproportionate number of lefties in your club to practice with. Or you simply stick with the sport long enough that the 15% of lefties you meet eventually adds up to a lot of experience.
