As one can notice many of the games as well as the behavior of some characters are very logical. For instance, Yokoya, he only acts according his own beliefs in a very logical pattern. His actions are by far the most easily foreseeable, aren’t they? He made a group based only in money factors and no trust because he certainly doesn’t believe in such a thing.
On the other hand, Nao is by far the most hard to foresee because you never know if she is going to lie for the good cause or if she won’t need to do that much. Don’t you think? Even though, her actions do have a remarkable pattern in them because of her wish. Consequently, one can foresee her actions as well.
Still, I would dare to describe her as a surprise factor for the game. For example, after she presented a clever explanation on Akiyama’s next movement to others during the musical chair game, she went to talk to Harimoto, but, in midway, she changed her mind and started talking to black ponytail. For me, this might be the key to Akiyama’s future plans on the present game that may decided this round game.
As for Akiyama, he might be very logical but he doesn’t behave as logically as Yokoya; probably, because of Nao’s influence which is not for bad but for good. Though he is still as sharp as an eagle what could be seen in his attitude towards the bald little man during musical chairs; as well as, his analytical statements about the true behind each game.
During a search on the net, I have bumped at a very interesting branch of psychology called Behaviorism which, in a certain way, relates itself with liar game.
Behaviorism is a psychological school that, in short, believes that anyone can learn anything as long as undergoes a strict regime willing to do it. According to the schools theory, for example, you can make any smoker stop smoking simply by associating the act of smoke with another very bad stimulus a couple of times. Although, this technic may fail whenever the guinea pig undergoes an accident with effects on the brain. Anyway, its idea is still somehow valuable in understanding the learning process.
In fact, our learn is based on patterns. We learn how to speak by the repetition of it. However, not only that, we also need the necessity/will. Both the pattern and the necessity makes one able to learn something. Both the repetition and the necessity are produced in the game process.

Man, it’s been long since I don’t post around here.
Behaviourism, huh? Which means, if I understood correctly, that people develop/learn due to: 1)necessity, and 2)repetition, which in the case of Liar Game, we could substitute for “influence”.
In other words: Nao’s honesty has influenced everyone around her, Akiyama and Fukunaga mainly, turning the former less cold and logic-driven, and the latter more trustful and less greedy. Hence, both of them are now less predictable than before.
Meanwhile, Akiyama has influenced Nao, giving her the tools to make her own theories and strategies, and Fukunaga’s influence has made her capable of lying and deceiving, regardless of whether it is for a good cause.
Because they all need all of these skills to survive in the Liar Game…
Interesting.
We come back to the whole “trinity” theme here, since I think that, so far, no one has influenced any other person this deeply. Well, maybe Abe-san has been “touched” by Nao’s character, but very briefly (I’m convinced this will really kick in later on). Yokoya is just too much of a loner to influence or being influenced; not to mention that he’d rather die than being influenced by Nao.
The one I think that has had the potential to shaken up everybody’s character pillars, and have not so far, is Harimoto. I felt kind of dissappointed when the musical chairs game ended and we hadn’t seen any real Harimoto action, as anticipated as it was. It’s been repeated many times: Harimoto appeals to the heart, that’s why he’s different from Akiyama or Yokoya. And that’s why he could have been the real challenge, a new element with which the great masterminds might have had to reshape their strategies. A new influence that Fukunaga himself wasn’t able to beat in the preliminary round.
Well, maybe it’s just me, but I didn’t see this during the Musical Chairs. Or am I missing something? Hopefully we’ll be able to appreciate it better in the next round.
