One of the great challenges in this world
-
is knowing enough about a subject
-
to think you're right but not enough about the subject
-
to know you're wrong.
-
There's like a gazillion hours of me on the internet.
-
In almost every case, I'm talking about the universe--
-
black holes, the big bang, time travel, God.
-
What I'm going to do in this MasterClass
-
is teach you how to think.
-
The goal here is to train your mind
-
how to see the world differently, how
-
to question what others say.
-
I've come to realize that there are three categories of truth--
-
personal truth, political truths,
-
and the objective truths that shape our understanding
-
of the universe.
-
The interesting thing about an objective truth
-
is that it's true no matter what.
-
Imagine that.
-
By the time we're done, you will be
-
equipped with some of the methods and tools
-
so you can turn data into information, information
-
into knowledge, knowledge into wisdom.
-
We all have susceptibility to bias.
-
Search engines on the internet are the epitome of confirmation
-
bias, and you're going to use that as evidence
-
that you are correct?
-
No.
-
The good thing about science is that it's true whether or not
-
you believe in it.
-
What does it mean to be skeptical?
-
What does it mean to be convinced by data?
-
A proper skeptic questions what they're unsure
-
of but recognizes when valid evidence is
-
presented to change their mind.
-
I will equip you to not only find objective truths
-
but then communicate to others how to get there.
-
It's not good enough to be right.
-
You also have to be effective.
-
The less connected you are to what is objectively true,
-
the less likely you will be able to make decisions
-
that will benefit your life--
-
your life, the life of your family, and even civilization
-
itself.
-
I'm Neil deGrasse Tyson, and this is my MasterClass.
