It's a comparison against others, not an independent and absolute rating. Assuming our sample population is not biased and is a fair reflection of society, then it does have to be normally distributed.

What this graph is saying is that, compared to others, most people are better at something. That's not possible. That would be like having a race and saying most people finished in 3rd place (assuming there aren't joint finishes).

As someone else pointed out, this is an example of the Lake Wobegon effect.

The question was "how do you compare yourself to others". Yet, the graph is not normally distributed but skewed to positive responses.

Unless the survey happened to pick an abnormally large group of the best present givers, it means that the people responding are overrating themselves.

They can't all be amazing!

Light always travels at the same speed. So, nothing slows it down, not even a black hole.

What mass does is warp space-time. This appears to "bend" light (the light is not actually bending but rather space-time is) that travels past it. Think of a stretched piece of plastic that has a metal ball placed in it. The plastic will dip in towards that ball. A marble rolled in a straight line on the plastic will, when getting near the metal ball, strart curving with the depression of the plastic. So the marble (analogy for a light photon, or could be a planet orbiting a star) is actually travelling in a straight line but the plastic is warped under it.

At the event horizon of a black hole, space-time is warped by the exact amount to prevent light from escaping.

The top 1% emit twice the total amount of emissions of the bottom half of the human race.

I'm not even hating on them here. I'm stating a fact and then saying that it's encouraging that they are realising work needs to be done and are, it would seem, putting their money where their mouth is. This is a good thing.
