This makes me happy.
I’ll let others elaborate.

That is the worst definition of expected value I’ve ever seen.

It’s a pretty terrible definition of “expectation” in its ordinary dictionary sense, let alone the mathematical construct.

Next time I am writing a glossary for technical documentation or a data dictionary, I am going to see if I can shoehorn in the nugget “xyz is exactly what you think it is”. Meh, who needs a job anyway…

Expectation:
If you’re walking down the street and encounter a black youth walking your way, you expect to cross the street to the other side. And if you’re foolish enough to continue walking on the same side as the black youth, your expectation can be negative, with possible loss of income or even a short visit to the hospital.

Expectation, sometimes written EV, is exactly what you think it is. For example, your expectation of purchasing this book is -$20. So long, suckas!

That’s true if you don’t read it, but most will at least attempt to read it so EV will be closer to -$100.

Is that including the specter of six-figure judgments and fees one may incur for critiquing the text online?

So the premise of the book is that it’s meaningful to talk about a single description of the weighted average of real world outcomes? So, if I play Russian roulette my expectation is, I dunno, a really terrible headache?

Honestly, it is simply a matter of statistics. We call it the Fundamental Theorem of Black Youth.

So nobody ever gets run over crossing neighbourhood streets?
I wonder what the EV is of crossing the street with your eyes shut. I know what the expectation is.
You can’t stop though, because if you stop, it would mean you made a Bad Gamble buying this book, from which it would follow that you need to read it to educate yourself on how to avoid doing this.

That’s just variance. Your expectation (sometimes referred to as “EV”) is that can you finish the book without slamming it shut in disgust and frustration, but sometimes it doesn’t work out that way.
Lol, which one of you is this?

That was me. I was impressed he actually let me get away with calling his book a work of historical fiction.
Lol yeah. Good work.
On the IDEOATv podcast they usually call something like this a book-like object.
