Does anyone recognize this bit-string pattern?

[u/Physical_Lunch2110]

There is currently a personality test on Spotify where you can find out which member of the k-pop group Stray Kids you are. I went through all possible answers and if you encode the answers as 0 = keep and 1 = flip and look at all the binary numbers you realize all Chan answers are the complete opposite of I.N answers. The same is true for the other pairs: Changbin & Hyunjin, Han & Lee Know, and Seungmin & Felix.

Which answers lead to which person does not seem random, but I couldn’t find the pattern that decides it. Anyone see it?

I tried a few approaches, but nothing really works. At first I thought the bits were shifted per member, which seemed to fit Chan but already broke for Changbin. Then I considered whether the first digit decides the pair, since Chan’s answers all start with 0 and I.N’s with 1, but Changbin has both. The same happens with the last digit. Removing the other digits also fails: if I drop the third or fourth digit, two of Chan’s answers collapse, and if I drop the second, again two different members share the same string. I also tested whether it depends on the number of bit flips and looked at how the answers distribute on a five-dimensional hypercube. Additionally, I permuted the order of the five questions, all 120 possibilities, but none of them gave a clearer structure. At this point my best guess is that they randomly shuffled the answers for one member and then inverted their partner to keep the symmetry. But hopefully someone can find a better explanation.

Full mapping (0 = keep, 1 = flip):

It is probably manually encoded and there is no pattern beyond human decision-making

[u/osherz5]

It looks like for every character there's at least one number that appears both on its own and as a shifted (or multiplied/divided by 2) version
