#1 is not a justifiable statement as written, #2 is true, #3 needs better terminology. Genetics does determine physical traits (physical traits are defined as phenotypes), heredity is about genetic variation. If you agree musical ability or

I must have misunderstood you above, we completely agree there; piano playing is not a physical trait. We are finally getting somewhere, it’s too bad this got too deep before finding a basis for productive conversation. The paper you linked

Oh you misunderstood me; I wasn't making any claims about what you said, I was only pointing out the logical conclusion that measuring acquired skills is not measuring intelligence, it would only be measuring effort & interest. I&#

Only if you keep people out of software. The broader meaning of politics used above is something like ‘the way groups of people make decisions’.

So why do you believe someone with 180 IQ is that much smarter than 100, if you agree there are no metrics to back it up? Surely there would be something that correlates with a two orders of magnitude increase in intelligence. Doesn’t the

> what exactly did you mean by that? Great question. My primary point was that the IQ scale and absolute intelligence aren’t the same things, and people often assume they are (this article’s premise, for example), or even worse many peop

Speaking of unsubstantiated claims… what evidence is there that intelligence can be trained? You’re confusing intelligence with IQ tests. I made no such claim that intelligence is bounded to 20%, you seem to have misunderstood. I pointed ou

I’m not measuring with IQ tests nor defending the use of IQ tests, the authors of the article implicitly accepted them as a valid measure or proxy for intelligence, and implicitly assumed that happiness surveys should reflect proportional I

by dahart 2mo ago
You can’t train human intelligence. It seems like you’re unaware of the goals and history of IQ. The whole point is to try to factor out learnable skills and measure pure cognitive capacity.

by dahart 2mo ago
Because intelligence is a physical attribute, and everything you listed is not a physical attribute and depends almost entirely on learned skill. None of those are physical limits of the body, and they change dramatically with practice. Mos

Again, that’s an overly literal and straw man interpretation of the golden rule that seems nearly intentionally obtuse. The rule is not suggesting you should do anything that you know other people wouldn’t like. Jumping people’s bones is

by dahart 2mo ago
That’s the awkward argument for being dimensionless. But we know we have units of angle because we have scale factors to convert between them.

> all angles are without a unit. Dimensionless, sure, but what do you mean here? Radians and degrees are units, are they not?
49.
by dahart 2mo ago
The reasonable assumption I was referring to is what the words in the golden rule mean, not what actions are moral or not. The golden rule is almost as far as it gets from a “specific fixed rule”, despite the name, and it doesn’t prescrib

Hehe, unfortunately that example undermines your otherwise good point, physical laws do not support your claim. Changing the units of a physical scale range does not change the relative position of a point inside that range, it only changes

Thanks! Okay this makes sense, and I have to agree interactive design with fonts & CAD does call for more control, and subdivision and resampling does often lead to lumpy, or just harder to manage curves. Personally I use splines mainly

by dahart 2mo ago
I’ve been fiddling with curves a long time and I haven’t seen the Q3A-Bézier reference - what are you referring to exactly? Is there some blog post, and was this about game programmers knowing about cubic Bézier curves? Most of the ‘general

I haven’t done any font editing but is this true in general? Sounds like some kind of application-defined constraint. You’re talking about quadratic splines with the shared approximating point between interpolating points, and probably quad

Yeah exactly. There’s an implicit assumption here that everything scales together in perfect proportion. This is a large and limiting and unnecessary assumption that undermines the argument somewhat. Maybe giant humans could exist with stoc
