I'm just dropping in real quick here to remind everyone that polygraph tests are complete bullshit popularized by a guy who
used them to shill razor blades and who is better known as the creator of Wonder Woman. Even the 80% accuracy figure given in this chapter is a massive overstatement of their efficacy trotted out by defenders of the polygraph, seemingly without recognizing that, even if this figure were true, a 1 in 5 chance of a catastrophic fuck-up is actually quite bad.
Oh, and I dig Spica's work hairstyle. Way to rock those braids, protagonist-chan.
