Chopstick team of your favorite TWICE idol? #VeritasiumContest

What chopstick team is your TWICE idol on, again? This is a short episode that explains the counterintuitive ways you should ask questions in order to figure out what chopstick grips someone has mastered.

All nine members of TWICE use chopsticks. Some of them have mastered two or more chopstick grips. While there are dozens of analyzed and documented grips, we'll use only 8 chopstick grips (aka chopstick teams) in this short video. We use a decision tree to determine which idols are in which chopstick teams, similar to how people tackle the "20 Questions" game and the "Guess Who" game.

The key to this game is learning to ask the right questions. The fewer questions you ask before you know an idol's chopstick team, the better. So how do you formulate your questions? It turns out that you should not ask specific questions in the beginning - it's like gambling. You may be unusually lucky once (pun intended). Or more often than not, your specific questions eliminate only a few choices from all possible choices.

Instead, always phrase questions to divide remaining choices into equal halves. But then that invite the next inquiry: how do you know what questions divide choices into equal halves? Well, like the realtors always say: research, research, and then some more research. Collect pictures and videos of chopsticking, and try to describe how they are similar or different. Many "factors" connecting or distinguish chopstick grips will surface over repeated analysis, and with increasing data. These factors can be tabulated, and used to find, given any population of chopstick grips (teams), a good factor that will evenly divide said population in half. That factor is the right question to ask, for that population of teams.

As for TWICE, there are 9 members wielding a total of 9 distinct chopstick grips. That is a coincidence. Some members such as Dahyun and Tzuyu wield more than one grip type. But we haven't encountered Momo's chopstick grip before. We looked at it hard for three days, and decided that we would not have enough time to analyze, document and name it before the deadline of Veritasium Contest. So that left 8 named chopstick grips in this game. And we were able to create a decision tree with only 3 levels, to determine chopstick teams of any TWICE member (except for Momo), since log2(8)=3.

This short 1-minute video is our second entry into the Veritasium Science Communication contest (#VeritasiumContest). It follows our first entry "Chopsticks are not 3rd-class levers": https://youtu.be/JVUAk0EYbqo. Details of the contest can be found here: https://www.veritasium.com/contest.

If this video piques your interest in this topic, head over to https://marcosticks.org/chopstick-grips-of-twice-members/ for detailed analysis of chopstick grips that TWICE members wield. This one-minute video left out a lot of nuanced details only found on the article. For instance, several members switches temporarily from Standard Grip or Idling Thumb to Turncoat, when pinching food. This is a common practice, it doesn't mean that they extend chopsticks apart using Turncoat. Also, Tzuyu does not technically wield Idling Thumb and Double Hook. Instead, she uses variants of these called Idling Thumb.5 and Double Hook.5.
