so it’s probably just some points assigned for the answers and maybe some simple arithmetic.

Why yes, that’s all that machine learning is, a bunch of statistics :)

I know, but that’s not what I meant. I mean literally something as simple and mundane as assigning points per answer and evaluating the final score:

// Pseudo code
risk = 0
if (Q1 == true) {
    risk += 20
}
if (Q2 == true) {
    risk += 10
}
// etc...
// Maybe throw in a bit of
if (Q28 == true) {
    if (Q22 == true and Q23 == true) {
        risk *= 1.5
    } else {
        risk += 10
    }
}

// And finally, evaluate the risk:
if (risk < 10) {
    return "negligible"
} else if (risk >= 10 and risk < 40) {
    return "low risk"
}
// etc... You get the picture.

And yes, I know I can just write if (Q1) {, but I wanted to make it a bit more accessible for non-programmers.

The article gives absolutely no reason for us to assume it’s anything more than that, and I apparently missed the part of the article that mentioned that the system had been in use since 2007. I know we had machine learning too back then, but looking at the project description here: eucpn.org/sites/…/Buena practica VIOGEN_0.pdf it looks more like they looked at a bunch of cases (2159) and came up with the 35 questions and a scoring system not unlike what I just described above.
