Think of the predominant opinions of past generations. I know that some people do still believe these things, maybe even you do. But they are no longer the predominant beliefs in much of the world, and are fading away in areas where they are still strong.

For example:
The earth is flat
The liver is the center of intelligence
Tomatoes are poisonous
Interracial marriages will create monster babies
Slavery is legitimate
Women are intellectually inferior to men
People in hotter climates are less intelligent
Wealth proves moral uprightness
Life spontaneously generates from non-life
Physical deformities from birth prove immorality in the family’s past
Now think of what the prevailing opinions are in your society now. Do you think they will be around in 90 years? Tell me what opinions and ideas you think will go by the wayside by 2100.
Let’s get an interesting list going!
