The hosts of Fox & Friends on Thursday encouraged their viewers to “be reasonable” by ignoring things like climate change, wage inequality, and ghosts — even if some of those things turned out to be true.

Fox News host Elisabeth Hasselbeck introduced Fox Business host John Stossel and his “Be Reasonable” segment by noting that “most Americans often ignore reason on some of the most important issues of our day.”

“A lot of Americans believe in ridiculous stuff,” co-host Steve Doocy told Stossel. “Let’s start with climate change.”

Stossel said that he believed that the “climate changes, always has, always will.” But he argued that a “climate catastrophe” was absurd.

“Every year, fewer people die from the weather because of fossil fuels,” the Fox Business host observed. “They are able to protect themselves. Big difference between ‘climate change is going to kill us,’ and ‘climate changes.'”

“So, you are saying that it would be reasonable to point out the pluses of fossil fuels,” Hasselbeck noted.

“In the short term, lives are being saved if the planet warms,” Stossel agreed. “There is some good evidence man contributes to global warming. But I say, so what? We can deal with that. It’s not a catastrophe. And cold is far worse for hurting people than warmth.”

Stossel added that other absurd things that people believed included ghosts, astrology and UFOs.

“What about wage war?” Hasselbeck wondered, referring to gender inequality in the workplace.

“It’s true, you women earn less than we men do,” Stossel replied. “But there are reasons for it. You, maybe, are more sensible. You have put more emphasis in not working in a horrible place, not working in dangerous places, you take time off to take care of a family. There’s a reason for that.”

“How do these ridiculous things get stuck in our heads?” Doocy asked.

According to Stossel, evolution had made humans “hyper-alert” in case there was a “saber-toothed tiger around.”

“As real or not as it may be,” Hasselbeck said.

The saber-toothed cat reference evoked a memory from co-host Brian Kilmeade, who had been quiet throughout most of the segment.

“As I remember in that series Land of the Lost,” Kilmeade remarked. “Do you remember that? That’s when the — yeah, Land of the Lost was afternoons on Saturdays… It was crazy to see men try to survive in times of dinosaurs.”

Doocy pointed out that viewers could watch more of the “Be Reasonable” segment during Stossel’s Fox Business show.

“Sometimes the ghost in your house will put the channel on,” Kilmeade quipped.
