The Word of the Year Is 'Post-Truth.' Let's Make Sure That Doesn't Happen Again.

In the months leading up to the election, president-elect Donald Trump asserted many fabrications as truth, including: that President Obama founded ISIS (with help from Hillary Clinton); that President Obama was not born in the United States; that climate change is a Chinese hoax; and that thousands of Muslims danced in the New Jersey streets after 9/11.

Mr. Trump is not the only one to take liberties with the facts. Fake news on all sides proliferated during the election season: Twenty fake news stories outperformed the top 20 real news stories in the last three months of the election.
