Details you don't need

Yesterday's post refers to a theory that sometimes has people asking...

If truth isn't the most important thing for staying alive and having kids, what is?

Our perception aids us in the following ways:

• find what we can do with something

• figure out what we can eat

• avoid what might hurt us

• helps us get mates (you can tell this works when you shoot lots of shots)

• saves energy by hiding the details we don't need
