(Abstract)

How much do you know about the world? Hans Rosling, with his famous charts of global population, health and income data (and an extra-extra-long pointer), demonstrates that you have a high statistical chance of being quite wrong about what you think you know. Play along with his audience quiz — then, from Hans’ son Ola, learn 4 ways to quickly get less ignorant.

Opinion:

I believe we are ignorant on the present because most of us focus on what we see around us and take it as a general condition around the world.  With this ted video we can clearly see that personal bias.

Besides, most of us don’t realize news is a point of view. The news bias lets us see what they want us to see in the way they want. We need to be critical and compare different newspapers. Like this our global vision will widen.

In fact, what I just said before, I’m sure most of us know it. The things we forget are the outdated facts. Things, years ago, were in a way but nowadays they not still being that way. We must not forget that things change as time passes. That’s why we have to know that what we think is what we are, including the world. If we think positive our world will be healthy.
