Why did Germany let in so many more immigrants than other European countries did? | It is not a choice. Most immigrants want to Germany. And since there are no boarders in the EU, once they are in the EU, they can go where they want. So Germany has two options: a) Taking the refugees. And asking other EU countries to take them, too. b) Taking the refugees. And not asking the other EU countries to take... |
Why is shampoo usually translucent but conditioner opaque? | Because conditioner is marketed as a "cream". We associate opacity with creaminess and moisturizing properties, while we associate clarity with cleaning properties.

Why is the human population almost 50/50 male/female? | /u/Teekno has given an accurate description of how the mechanics work. However, that doesn't explain why the mechanics are the way they are.

Why is Rotten Tomatoes scores always higher than Metacritics? | RottenTomatoes doesn't rate movies in the normal sense, the % is just the percentage of critics/reviewers who gave a positive review.

Is a 2.5ºF temperature change significant? | As [xkcd] points out, the last ice age was "only" 4.5 degrees Celsius colder than the global average.

Why do we feel bad after a short amount of sleep? Shouldn't we feel more rested regardless of the amount we got? | So I found a website that explains the phenomenon really well.

Other than supply and demand answer: why are colleges in America so expensive? | I think supply and demand is an incomplete answer. There are other market modifiers in place.
