Psychology is about as far from philosophy as you can get. It relies almost exclusively on experimental evidence and rigorous operationalization of concepts. Similarly the medical sciences are having lots of trouble with nonreplicable resea

People tend to use the terms "consulting", "freelancing" and "contracting" almost interchangeably, though.

What exactly bugs you about AUC? What about ROC curves?

Not necessary at all. You can teach most of the interesting parts of statistics with just the binomial distribution and numerical techniques like bootstrapping. Nothing about that is wishy-washy, it's just a modified curriculum that si

R is very much like JavaScript. It's not exactly love at first sight, but it has enough features to make it palatable (vectorization and first-class functions), some wonky parts that can work in your favor if handled with great care (n

Relax. Anyone who writes software will code themselves into a mess sometimes. Learn to love refactoring.

Wouldn't the sheer pointlessness of it all bother you after a while? If someone wanted to pay you to dig a ditch and fill it up again, for the right price, would you do it? I mean, I'm not trying to claim that working for that hot

I think in Europe people would view higher education as both enrichment and an investment in your future. The issue they becomes how to calculate return on investment on something that's 20%, no wait 35%, or is it 30% a hobby and 80% o

A better understanding of addiction is the key to effective treatment – and treatment really isn't very effective right now – so the question is whether the harm from any increased stigma is offset by the benefit of better treatments.

A while back on HN someone linked to "Most People With Addiction Simply Grow Out of It" [1] and "Here’s What I’ve Finally Concluded About 12-Step Programs" [2], which argues that many of the ways in which we try to treat

A large amount of published results that are wrong is definitely something science can live with: we have to trade off Type I against Type II. But we should value accuracy: if we report something as being very, very unlikely if chance was a

I smell needless dichotomization. I'd rather teachers and parents didn't give up on students just because part of their mathematical aptitude might be genetically determined. Until you've pried apart nature and nurture, give

You could draw the multiplication of e.g. 1/2 and 1/2 by dividing half a pie into another half. But you're right, it's harder in many cases and impossible in some.

FWIW, this is certainly not what people who do research into how to teach math advocate. In fact, one of the recommendations for teachers is that they should try to get students to come up with the algorithms themselves, or to "guide&q

The trouble with traditional homework is that you have to wait a long time before you get feedback, at the earliest it'll be the next day. This makes it hard to correct misunderstandings. So parents helping with homework is a great ide

Another thing is that even very basic math concepts can be hard to explain in a way that makes sense to kids. For example, if you have to explain why multiplying unlike fractions works one way whereas adding unlike fractions requires an ent

The line of an ordinary least squares fit would go from approximately 50% on the left to 70% on the right or maybe a little bit less steep than that.

Yep, that, and the regression seems to be forced through the origin, which is stupid. And the dependent variable is on the X-axis. All pretty weird choices.
