Why do people believe we only use 10 percent of our brains?

You've probably heard the popular claim that humans only tap into about 10 percent of their brainpower. (Via Getty Images)

Neurologists have debunked that urban legend countless times in the past, with many calling it a laughable and completely false myth. (Via Scientific AmericanNBCBBCLiveScience)

But for whatever reason, people have still chosen to believe it. And the entertainment business might be, in part, to blame.

"It is estimated most human beings only use 10 percent of the brain's capacity." (Via Universal Pictures / "Lucy")

In the new sci-fi thriller "Lucy," which hits theaters this weekend, Scarlett Johansson plays a woman who is implanted with a mysterious drug that increases her mental capabilities exponentially. (Via IMDb)

And other recent releases like "Limitless" and "Transcendence" give the idea we only use a fraction of our brain's computing power.

But as "Lucy" starts to make people question this idea's validity once again, doctors are reiterating — it just doesn't make sense.

Samadi says, "It's not true, absolutely not. We're using 100 percent of our brain all the time." (Via Fox News)​

Except, perhaps, on Monday mornings. No one knows for sure where this popular "10 percent" myth originated.

But a professor of clinical neuropsychology at the University of Cambridge told the Belfast Telegraph the 10 percent figure was widely circulated for the first time in the 1936 best-seller "How to Win Friends and Influence People."

She claims the author probably made up the figure to prove a point in the book. (Via Amazon)

But that 10 percent number could also come from a misunderstanding of how most of our brain cells work.

SAMADI: "What's interesting about this is that, if you get a brain scan, you would see that maybe about 10 to 15 percent of your brain is extremely active." (Via Fox News)

To be clear — the entire brain is always active. As LiveScience pointed out back in 2010, brain scans have shown that people use all of their brains, though it is true that we don't use all of it at the same time.

But years of studies like that don't seem to be getting through. A survey sponsored by The Michael J. Fox Foundation for Parkinson's Research last year found 65 percent of Americans still believe that people only use 10 percent of their brains.

So why won't people let this myth go already?

A health writer for the BBC says it might be because it's a pretty encouraging idea. "Maybe it's the figure of 10 percent that is so appealing because it is so low that it offers massive potential for improvement. We'd all like to be better. ... But, sadly, finding an unused portion of our brains isn't the way it's going to happen."

Hopefully, the film industry will catch up with the world of science soon. But hey, at least it still makes for a good movie night, right?

  • France's attempts to counter the radicalization of its young people are in turmoil, with a group home intended to turn them away from Islamic extremism empty, the head of a highly publicized nonprofit convicted of misuse of public funds, and plans to segregate prison inmates suspected of harboring jihadi ideas abandoned. The results are both disappointing and unsurprising, according to a French senator who co-wrote a recent report highly critical of an effort she says was devised in haste and has been a waste of money. 'We spread money around because we didn't have time and we had to communicate something, we had to show something,' said Sen. Esther Benbassa, whose report last month concluded that the country's de-radicalization efforts so far were largely ineffective. 'The time that this takes to work is long, very long.' The backtracking takes on added significance as recent attacks, including last week's rampage in London and the previous week's assault on soldiers at Paris' Orly airport, were carried out by ex-convicts who may have been radicalized behind bars. France is not the only country reconsidering how it responds to radicalization. Britain's contentious Prevent program, which seeks to identify residents at risk of being radicalized, has come under criticism by rights groups and an expert for the United Nations who said it stifles free speech.
  • Leaders of the Senate Intelligence Committee investigation into Russian meddling in the 2016 U.S. elections vowed at a joint news conference on Wednesday to conduct a thorough and bipartisan probe, clearly setting themselves apart from their House counterparts, who are locked in a bitter, partisan struggle over the course of their review. “The committee will go wherever the intelligence leads us,” said Sen. Richard Burr (R-NC), the Chairman of the Senate Intelligence Committee. “We’re here to assure you – and more importantly the American people who are watching and listening – that we will get to the bottom of this,” said Sen. Mark Warner (D-VA), the top Democrat on that panel. Without going into much detail on who might be in for questioning when by the committee, Burr and Warner set out the basics of their probe, saying seven full-time staff members are spending weeks going through documents of the Intelligence Community on what Russia did in 2016. Sen. Mark Warner on the Senate intel committee Russia probe: 'We're gonna get it right' https://t.co/unNRqnks5q — CNN Politics (@CNNPolitics) March 29, 2017 Burr described the review as, “challenging to say the least,” as both men made clear this was turning out to be maybe their most important duty – ever – in the Congress. “This is one of the biggest investigations that the Hill has seen in my tenure here,” said Burr, who was first elected to the Congress in 1994. Sen. Burr on intel committee's Russia probe: “We weren’t given a free pass to do a witch hunt.' https://t.co/fo3n6WsdDC — NBC Politics (@NBCPolitics) March 29, 2017 The cooperation among members on the Senate Intelligence Committee stands in stark contrast to the infighting and finger pointing going on across the Capitol on the House Intelligence Committee. “Our investigation is stalled,” said Rep. Eric Swalwell (D-CA), as he blamed panel chairman, Rep. Devin Nunes (R-CA) for canceling a variety of meetings set for this week. “I think he needs to recuse himself,” Rep. Jim Himes (D-CT) said of Nunes, as Democrats furiously contend that the sprint by Nunes to brief President Trump last week on intelligence – which he still has not shared with his committee – signals something is wrong. On the other side in the House, Republicans don’t see anything wrong with the work of Nunes, and argue Democrats are pushing conspiracy theories that have no evidence behind them. “This is media speculation being fueled by Democrats,” said Rep. Peter King (R-NY). Rep Turner (R-OH) a Republican on the House Intel Cmte asked on @MSNBC if Chairman Nunes should recuse himself: 'absolutely not' — Alex Moe (@AlexNBCNews) March 28, 2017 But over on the Senate side of the Capitol, some fellow Republicans have made clear their displeasure with the actions of Nunes over the last week – and at today’s news conference – Burr and Warner made clear they were running a different operation. “We’re not asking the House to play any role in our investigation, and we don’t plan to play any role in their investigation,” Burr told reporters. Thursday will bring a public hearing for the Senate Intelligence Committee that will focus on what Russia has been up to on the internet, using the opportunity to warn European nations what they may face when they hold elections in coming months. “I think it’s safe by everybody’s judgment that the Russians are actively involved in the French elections,” Burr said, giving one example.
  • Moments after opening fire on three suspected burglars inside his home just outside Broken Arrow Monday, Zach Peters called 911. [HEAR THE 911 CALL HERE] KRMG has obtained a recording of that call, in which Peters tells the call taker he shot two men, and “I believe one of them’s shot bad.” Peters thought he had only hit two of the suspects when he opened up with AR-15 after hearing them break into the home. But as it turned out, all three of them died on the scene. Wagoner County deputies identify them as Maxwell Cook, 19, Jacob Redfern, 17, and Jaykob Woodruff, 16. A fourth suspect, who reportedly drove the trio to the home with the intent to burglarize it, never entered the house. Elizabeth Rodriguez, 21, later turned herself in at the Broken Arrow Police Department. The District Attorney is reviewing the case to see if Peters might face any charges, but investigators indicate they think that unlikely.
  • A paralyzed man was able to feed himself for the first time in eight years, after doctors implanted sensors in his brain that sent signals to his arm. Bill Kochevar was paralyzed from the shoulders down after a cycling accident in Cleveland in 2006. To help him move again, in 2014, doctors surgically placed two tiny implants into his brain to pick up signals from neurons from the area that controls hand movement. The signals are relayed through external cables to a computer, which sends commands to electrodes in his arm and hand muscles. After first practicing with virtual reality, Kochevar was then able to drink coffee through a straw and eat forkfuls of mashed potatoes and macaroni and cheese on his own. 'It was amazing,' the 56-year-old Kochevar said. 'I couldn't believe I could do it just by thinking about it.' But after years of being paralyzed, Kochevar's shoulder wasn't strong enough to lift his arm, so doctors also provided Kochevar with a robotic arm support for extra assistance. Kochevar's case is detailed by his doctors in a paper published Tuesday in the journal Lancet.
  • A project to resurface nearly six miles of US-75 in Tulsa is scheduled to start Monday, April 3 and will have a major impact to traffic through early summer 2017.  ODOT told KRMG the project is to resurface both directions of US-75 from near the western I-244 junction (Red Fork Split) to near the Creek Turnpike/SH-364 junction.  Various lane and ramp closures can be expected throughout the project. Due to the time needed for patching work and for the type of overlay, there will lane closures in place during peak travel times.  Drivers are urged to plan ahead for significant delays in this corridor, especially during the morning and evening commutes, and should seek an alternate route if possible.  Click here to check the traffic before you hit the road.
