What would be some fact that, while true, could be told in a context or way that is misinfomating or make the other person draw incorrect conclusions?

Ah, survivor bias. Reminds me of analysis of damage to bombers in WW2. Data showed most damage was done to the wings and body of planes. The tail, cockpit and engines were rarely damaged. They responded by reinforcing those areas that were frequently damaged.

However they were only observing bombers that made it back to base and so data on planes that were shot down was missing. Luckily someone did eventually realise this and so the research could be used as evidence that strikes to the areas rarely recorded indicated a downed plane.

I don’t know if this counts, since it’s only a “true fact” if you are fine with carefully chosen words and the omission of crucial information…

But the 13-50 stat is dangerously misleading.

You know,

Black people make up 13% of the population, but 50% of the violent crime.

Black people in America do, in fact, make up 50% of the murder arrests according to FBI crime statistics

That much is true.

But certain people tend to use this fact to assert that police officers are far more likely to be killed by black people than by white people. Therefore, the stats that show them brutalizing black people at a higher rate – since they fall short of that 50% number – are evidence that they hold back around black people to avoid appearing racist.

The users of this stat heavily imply black people are more violent and murder-prone, and hence a greater threat. The argument also carries with it an implied benefit to eugenics or a return to slavery (to anyone paying attention.)

But no one using this stat ever explores potential causes for the arrest rate disparity, instead letting their viewers assume it comes from “black culture” (if they are closeted racists) or “bad genes” (if they are open racists).

There’s no attention paid to the fact that black people make up over half of overturned wrongful convictions

There’s no attention paid to the stats further down in that same FBI crime stats table that make it clear that black people make up 25% of the nation’s drug arrests, despite making up close to 13% of the US’s total drug users. (Their population’s rate of drug use is within a margin of error of white people’s rate of drug use). It should be strange that a small portion of the perpetrators of drug crimes make up such an outsized portion of the total drug arrests in this country. But the disparity doesn’t even get a mention.

There’s no attention paid to the fact that more than half of US murders go unsolved, meaning even assuming impartial sentencing and prosecution, we would only know black people committed 50% OF 50% of the murders – 25%. And in a country where 98% of the land is owned by white people and the public defender system is in shambles? Which demographic do you think would be able to afford the best defense, avoiding conviction even when guilty, and ending up overrepresented in the “unsolved murder” category? If only 50% of murders end in a conviction, that means every murderer who walks into a courtroom has a solid chance at getting away with it. Even more solid if the murderer belongs to the richest race. The murder arrest rate by race winds up just being a measure of which demographics can afford the best lawyers, rather than any proportional representation of each demographic’s tendencies.

They mention none of that. The people hawking this statistic intentionally lead their viewers to assume, “arrested for murder” is equivalent to “guilty of murder.” And that 50% of the murder arrests is equivalent to 50% of the total murders. The entire demographic is assumed to be more dangerous.

The thing about this is that the kind of people who quote statistics like that typically don’t have an interest in all of that. They start with a racist assertion, then search for anything that appears to corroborate. They have no interest in actually understanding the statistic, they only care about it insofar as they believe it justifies their racism.

That, or they know it doesn’t and they’re purposely arguing in bad faith.

Yeah… that’s a pretty reasonable conclusion. It’s hard to just state outright though, when I live with the exact sort of person described in your comment.

It’s interesting: the people who are fine with calling an entire race murderous seem to take great umbrage at being considered “racist.”

It’s the r-word to them – a slur used to invalidate their concerns and diminish the importance of their well-being.

That their concerns ought to be invalidated – since they are the racist result of racist fear-mongering – is never well-received.

The real bottom line is that when you create an underclass of people whose neighborhoods get firebombed or bulldozed when they get too affluent (see e.g. “Black Wall Street” in Tulsa and Auburn Avenue (formerly “the richest Negro street in the world”) in Atanta, respectively) and had generations of absent fathers due to persecution for things like “vagrancy”, of course they’re going to stop giving a shit about laws that bind but do not protect them! It’s entirely rational that people systematically excluded from being able to get ahead while acting within the law, and whose behaviors are deliberately criminalized in order to target them, would end up committing crimes at higher rates than the people benefiting from their oppression did. In other words, even if it’s true that they actually commit crimes at higher rates (as opposed to being accused at higher rates or being less likely to avoid conviction, as you pointed out, which just make the statistical bias even worse by compounding on top), even that is disingenous because it ignores that the disparity is caused by classism and institutional racism, not anything intrinsic to their race itself. The fiction that it’s somehow their own fault is like a society-wide version of “stop hitting yourself.”

Oh 100% this. The main accomplishment of Tulsa and Auburn was keeping black people impoverished, and…

“About 60 [academic] papers show that a very common result of greater inequality is more violence, usually measured by homicide rates,” says Richard Wilkinson, author of The Spirit Level and co-founder of the Equality Trust. - source

For as long as society insists on high inequality with one race forcefully held at the bottom, no rational person can expect that race to be peaceful.

It’s just… I have a hard time bringing this concept to the table in a debate with people who believe “personal responsibility” can somehow magically indemnify society against its impact on people.

In fact, I am generally speechless when debating such people. It’s such an alien worldview to me. How can personal responsibility actually make society irrelevant? And since when?

The kinds of people who spout the 13-50 argument basically believe NOTHING society does can increase or decrease murder (except, when convenient, being “too soft on children” or “soft on crime.”)

Light roasted coffee has more caffeine than dark roasted coffee.

Technically, per bean, more of the caffeine is cooked out of the dark roast. However, other things are also roasted out of a dark roast to the point that the individual beans are also lighter and smaller. When brewing coffee, usually you either weigh your dose of beans out, or you use a scoop for some consistency. Either method will result in more dark roast beans ultimately making it into the brew than would with a (larger, heavier) light roast.

Typically, this more than cancels out the reduced caffeine content per bean, so a brew of dark roast coffee still typically has more caffeine in it.

If I remember correctly, dark roast was also originally devised to hide bad-quality coffee beans. Nowadays it is often implied that darker roasts are better, which actually isn’t necessarily the case.

Dark roasts have a more consistent taste/flavor and it has a longer shelf life, so it’s easier to know what you’re getting. If you want to taste the variety of flavors coffee can have, you’ll go for fresher lighter roasts.

Thank you for laying it out like this. I’d often heard that about light roasts, but had never noticed any difference in my caffeine response when I switch roasts. At any rate I’ve always preferred dark for the flavor, but it’s good to know I’m not sacrificing any buzz for it!

I remember looking this up and the difference is around 1%, so if you’re worried about caffeine intake you’re better off leaving a mouthful in the bottom of your cup than changing beans.

I’ve honestly never thought of that. Guess that’s why I’ve not been able to feel a real difference in my morning coffee when I use different roasts. I always thought “well it can’t be losing that much caffeine because it doesn’t feel any different than my medium or light roasts.”

As ice cream sales in the United States increase, so do deaths in in developed parts of Africa.

I use this fact to explain to students how true information can be used to mislead people into drawing wild, deranged conclusions.

The commonality in these events is the rise in temperature during the summer. But if you leave that out, there’s an absurd argument to be made about how purchasing ice cream is inherently evil.

I don’t think it’s an amazing example of what OP is talking about, but as an example, I like how simple and easy to follow it is. Great for junior high level kids.

So there’s some “incorrect” assumptions you have made about the North American summer, and weather in Africa. In the North American summer, only North Africa experiences summer with you guys. The rest of the continent is blanketed in rains (West, Central and East Africa) or are in outright winter (Southern Africa). So our temperatures do come down in your winter. Your coldest months are our hottest months for most of the continent (except for North Africa). So saying the developed parts of Africa
