My caveat to this answer is that it would be hard to disprove that video games can lead to increased depression/anxiety/aggression in certain individuals since there will be at least some individuals that are more prone to these effects compared to the rest of the population. So I want to specifically address the elements of the claim that are generally ...

As others have pointed out, there are problems with the original questions, but that does not invalidate the original idea. A primary usage of contraceptives is to prevent children, and we know they are rather effective at this. And apparently "The divorce rate among couples with children is 40 percent lower than couples without children" [1]. I have been ...

There are many specialty steel variants, and no doubt at least some of them are patented by Australian firms and therefore cannot be sourced from other places. Also, the exact composition of the raw materials (any source will leave its trace contaminants) can have an effect on the resulting alloy, and Australian steel mills are going to source their raw ...

Not really ; mixing zinc and aluminum in steel coatings has been around over 40 years. Different compositions will have different physical and chemical/cathodic properties , anyone can claim theirs is the "best". Look in Woldmans' Alloy Index; of the many thousands of listed alloys,possibly half can be called some type of carbon steel - It doesn't take much ...

3.2% sounds somewhat good, but notice that the quoted failure rates are per year, not per couple. For a couple using this method, over a ten year period, there is a 28% chance of at least one pregnancy, over twenty years it is 48%, and over twenty-five years it is 56%. 100% - (100%-3.2%)¹⁰, 100% - (100%-3.2%)²⁰, and 100% - (100%-3.2%)²⁵ So, even if ...

No, the Milankovich cycles drive the recurring ice ages that happen since the Antarctic got isolated from South America and iced down. They are all too slow to influence the climate in mere decades. The fastest of the Milankovich cycles run in 11 000 year intervals. This means that the well-known curves that show a correlation between temperatures and CO2 ...

There have been about 50 studies of sex and age correlations in EI metrics.(e.g., Day & Carroll, 2004; Lumley et al., 2005). Even so, scientists cannot agree if the variance is 1% or 4% for sex difference, and 3% or 15% for age difference. Age varies EI more than sex. There have been comparisons of EI scores of racial groups in the US. Studies suggest ...

Are military spy satellites as advanced as people think they are?

We've all been there: you're discussing the recent launch of a rocket carrying a satellite to orbit, or what have you, and suddenly someone pops in and makes a comment like Yeah, it's amazing and ...

There is something called retroversion or anteversion of the uterus. The uterus, as can be seen in the second and third pictures of Andrew Grimm's answer, tilts either towards the front of the body (anteverted uterus) or towards the back (retroverted uterus), in which case it stands up nearly straight. When I was young and reading women's magazines in The ...

The claim is both misleading, and wrong from an objective point of view. First, it is misleading because the numbers it refers to are the country's mean download speeds. In the objected countries, such as e.g. France (or even moreso Canada), a large number of people lives in rural, sometimes quite remote areas where, indeed, internet speeds are not always ...

This is answerable only within particular context of what does it mean for country to have an internet speed X, therefore the original presumption and question is not very meaningful, unless you specify what exactly are you measuring. In general, we could reasonably expect that UK will have availability of faster internet in general (more high speed lines ...

Several answers provided data about Madagascar in particular. Here is a more general explanation why it's not surprising. Poorer countries generally tend to have better internet connection at the moment, mainly due to the more developed countries having started building their infrastructure sooner. Technology and the speed of network connections improved ...

Malays are an ethnic group that established itself in the Malay Peninsula and slowly spread to parts of Borneo and Sumatra. They are essentially a hybrid of 3 main groups of people that arrived from mainland South East Asia and to a lesser extent people from South India and South East China who arrived much later by way of the Philippine Islands and Borneo. ...

@Evargalo gave an excellent answer proving the numbers, but it's interesting to look at what drives this. The fact that this is true may be very surprising, but less so once you consider world population and world economic activity. There are literally people alive today who were born when there was less people in the entire world than there is in China ...

Having taken a bicycle safety course, I can attest to part of the syllabus in which they explain why bicycle lanes are less safe than operating as another road user / vehicle operator. As a proponent of these courses, I operated in that manner and have personal experience for both methods. Bicycle lanes are unsafe compared to conventional road operations. ...

Possibly. There have been many advances in acoustics, especially in the application of ultrasound, that may explain that incident in Cuba. The Incident In 2017, US diplomatic staff began to suffer mysterious traumatic injuries that have now been dubbed “Havana syndrome” by the US and Canadian media. The diplomats stationed in Cuba initially referred to the ...

For now no, because we have not found something that could be solely a flying vehicle beyond doubt.

I think the premise is a bit backwards here. The most direct and shortest answer is: No, it does not depend on so much artificial fertilizer. "A uses B" is not the same as "A depends on B". The plants are not going to die if they have no synthetic fertilizer applied. 1) Non-synthetic fertilizers could be used. There is nothing to cite here, as that would be ...

There are a lot of formulas that look simple. "The absolute error is less than 0.00004" (actually that's the relative error) basically means that the first four digits match (when ignoring the location of the decimal point). So the chance of two given verses matching a given formula to this extent by random is about 1e-8. On the other hand, the Bible has ...

Short Answer: True. Every year, in time for Davos (i.e. the Annual Meeting for the World Economic Forum), Oxfam releases a report about the state of inequality. Here's a link to their latest.

That statistic is at least plausible, and likely true. Children have essentially no wealth, so to start out the richest are already ahead of about 25% of the world (about 1.9 billion people) simply by having a positive net worth. The next 1.9 billion is made up of the impoverished adults, young adults that are just starting careers, working class populations,...

Right idea, wrong target. We have a pretty good idea which Russian diplomats are affiliated to their various intelligence agencies, and they ours—without help from Snowden. That's how we know whom to expel. Note we didn't assassinate them. I recall in 1975, an American columnist identified a Soviet "journalist" known as Yuri Barsukov as a top spy. (I ...

No. I personally lived in Houston for several years and I drove that stretch of road many times. It is definitely not 26 lanes. Here's how the Houston Chronicle contrives that number (and I still come up short on my count): There are only 4 thru lanes in each direction for a total of 8. There are an additional 2 interchange lanes in each direction, used ...

Nope. It just looks like. The average main freeway lanes are 8 lanes. The toll lanes are 4 lanes. The frontage lanes are 6 lanes. Where there's acceleration lanes are 10 lanes. It then averages to 18 lanes. Where there's acceleration lanes will be 20 lanes. However, the West Loop north of the Katy Freeway is wider since reconstruction is done with. By this ...

No Science does not define life as "beginning at conception", because science does not, to any satisfactory degree, define "life" in the general case: There is no broadly accepted definition of 'life.' Suggested definitions face problems, often in the form of robust counter-examples. Here we use insights from philosophical investigations into language to ...

A bath tub has a capacity of around 110L. An average 80kg person has a density of 1010kg/m3, therefore a volume of 0.08m3 or 80L. Let's say the person is only 50% under water when taking a bath. That means around 70L of water are poured in the bath tub so that it's full to the rim when one person is sitting in it. Compare with a shower. A typical shower ...

I paid close attention to the Fukushima investigation for years. I've lost my sources (I could use some help with that) but I can add some more detail as to exactly where it went wrong.

In a nutshell, "I am a simple employee and I want to critic my boss. Why? Reasons!.". So everybody talks against bosses, it's practically routine. Now, about the topic, one explanation.

Technically no. The best speed is the speed with a better ratio of consumption/distance. Usually (it depends on the vehicle) it's around from 50km/h to 80km/h. Reducing the speed will decrease the emission but increases the time the vehicle is polluting. For example, a parked car with the engine running still pollutes.

There are two different claims being represented in this question, that the church engage[s] in a significant number of lawsuits over incidents at their activities and implicitly, that the church deliberately provokes people to beat up its members. I don't know about the first claim, but the second claim is definitely not true, and could only be ...

An analogy: suppose there's a long line of swings. You run along the line, pushing each swing as you go. This will result in each swing being slightly out of phase with the one before it. There will be appear to be a "wave" traveling down the line of swings at the same speed that you ran down it. For instance, if you look for a swing that at its maximum ...

The claim here is that Michael Cohen's sentence was already reduced by Robert Mueller's (special counsel) prosecution team. Cohen then has to continue to tell the same story, including to Congress. If he told a different story, he could be prosecuted (again) for lying in his allocution (for our purposes here, his confession under oath when he plead guilty) ...

It is worth noting that the name or word "Nazi" does not appear in Hitler's book My Struggle [see Hitler, Adolph, Mein Kampf, translated by Ralph Manheim] nor does it appear in the speeches of Herman Goering [See Selected Speeches of Field Marshal Hermann Goring, available on Amazon Kindle]. Hitler Youth leader Melita Maschmann wrote a book about her ...

@Tom77's answer is correct, in that the speedometer must be designed to already read a little high to avoid ever reading lower than actual speed. However, that rule only applies to the speedometer on the instrument cluster. Often there is a second speedometer based on the car's GPS unit that is part of the navigation system. Some systems can display it, e.g....

It seems likely to be true. In particular, Starboard Value made the claim as part of an extended, savage, and heavily reported critique of the then-management of the chain, where the "no salting" bit featured heavily in the reportage. The attack was clearly and openly being made as part of a takeover attempt. (https://www.sec.gov/Archives/edgar/data/...

No, it is not fair to say that "a missed telegraph pole delivery" was "what caused" World War II. Even if we are willing to give the Joker the benefit of doubt, that he meant "one of the causes", the impact of that one missed delivery is much less significant than The Joker, or the web articles you quoted, imply. Poincare's decision to invade the Ruhr came ...

While the statement is generally true today, as other answers have explained in detail, it isn't certain that it will always hold true in all physically demanding sports. Of courses it is difficult to say "never", but there is some evidence that women may eventually match or even exceed men's performance in certain endurance sports such as ultra-marathons. ...

The short answer is that more medical interventions and higher spend do not automatically improve the outcomes for patients. Instead of spending more, healthcare system should be spending smarter.

What specific claims are considered quackery, and why? Pretty much all of it. The referenced page from "Altered state newsletter" is solid woo.
