After seeing no code in their repo I was interested in the same. The important parts are in https://stealingurfeelin.gs/js/events.min.js

You've left out some important parts of the iq calculation, with the full equation being:

    reactions = dogPos + Math.abs(menPos - womenPos) + Math.abs(whiteNegative - nonWhiteNegative) + kanyePos) / 4;
    iq = Math.floor(15 * -((reactions - 0.0005) / 0.05) + 100);
    if (iq < 100) {
        thatPartBitSFX.play()
    } else {
        thatPartWaySFX.play()
    }

Also amusingly rebulican percentage is calculated as:

    reactions = (dogPos + kanyePos + nonWhiteNegative) / 3;
    republicanPct = 50 + 15 * ((reactions - 0.05) / 0.1),

And income is calculated as:

    reactions = (iq / 100 + republicanPct / 50 + dogPos) / 3
    estimatedIncome = Math.floor(200000 * (reactions - 0.5) + 31099),
    if (estimatedIncome < 31099) {
        isPoorSFX.play()
    } else {
        isNotPoorSFX.play()
    }
