How two brains can synchronise and why it matters – BBC News

Is collective intelligence more important than IQ and what exactly does it mean?

Internationally-acclaimed neuroscientist Dr Hannah Critchlow explains why brain synchronicity – the ability of two different brains to match their electrical brainwaves – is crucial to our future.

Dr Critchlow is based at the University of Cambridge and is the author of Joined Up Thinking: The Science of Collective Intelligence and its Power to Change Lives.

    brain is very very good. I'm a coach about power of brain through breathing exercise. My student can read, play bicycle and another without the eyes. this is no trick or magic, this is real use your brain.

    I've read somewhere men are massively over-represented in high IQ societies. Could this be an effect of male brain synchronisation rather than a scaling effect of the smaller average female brain?

    A thought of having my thoughts read by others scares the bejesus out of me!

    Remember the lines from it's alrght, ma by Bob Dylan

    "And if my thought-dreams could be seen
    They'd probably put my head in a guillotine."

    You can see the collective and synchronisation now. all the strikers are a huge collective and commiting a synchronised ransom of the taxpayer and gov…

    Women the biggest synchronisation in years…

    look what happened to birmingham city council…

    A collective of wasteful glutons….

    This sounds suspiciously like Rupert Sheldrake’s 1981 theory of morphic resonance. Essentially, some humans, in line with many animals, can access a form of shared consciousness and thus utilise the experience of other humans subconsciously. I think these people were called “Savants” in Victorian times.

    They’re saying right now that they blamed me because I couldn’t keep my mouth shut about some underground project having to do with this. Listen to me, then you didn’t deserve to be synchronized with me.

    Sometimes a good leader helps especially in a group of individuals regardless of gender or IQ.. The Common sense factor is also a necessity especially when the shit hits the fan.

    Very interesting. Especially the part that highlights how important females are for the functioning of a group of people.

    I don' t mean to make an anti-man statement. Although that can be hard.
    But in my life, 38 years worth of experience, observation and learning, i noticed some things.

    I' ll try to limit it too two things too keep it short.
    First of all, i am not smart. I just know some things.

    Second, most teachers, doctors, social workers, psychologists, nurses, (and a growing number of police officers and soldiers), the people that teach, care, help and protect… are women.
    (In my country at least.)

    Now we can' t all be females loving females, we need males too. But it sure would be nice if young boys were tought more often to listen.

    And i' ve lived in both worlds. I do not miss the environment where it was mostly about competition, agression, dominance… i prefer communication, kindness, compassion…

    Now i' m surrounded by sisters and i do feel like our brains synchronize when we are spending time together. Curiously, i am not even a group person, i spend almost all of my time alone. But place me in a circle of friendly, open minded people and i will get in your head and you into mine.

    I do not like our species in general but i ❤ that experience.

    This comes across as pro hive-mind propaganda. “This way to The Singularity, boys and girls. We won’t have any geniuses so you better learn how to connect your chimp brains and work together!”

    Amazing, the BBC finally realizes that intelligence has been on a decline for a century now and they ignore it and load it up with pseudo-science like gender ratios and c-factors lol.

    Twitter fired most of their employees and got better because the fixation on being in sync is parasitical in nature.

    This is Lysenkoism employed for Progressive purposes. Why? According to this obvious nonsense if you put 20 people(with the perfect gender ratio) with IQ of 100 in a room they will solve a problem faster than a Physicist working alone? 😆

    The irony of course that the lions share of technological progress(as in epoch changing ideas) are usually produced by brilliant geniuses, granted sometimes they’re working in teams of other geniuses. Manhattan project for example , even then it took exceptional creative genius above all the others(Von Neumann) to solve a crucial puzzle.

    Egalitarian societies cannot brook the fact some are born with the “right stuff” and the vast majority are not.

  24. @randomsongsinlocrian

    This is what we call "Lysenkoism" – or ideologically motivated pseudoscience. How can "collective intelligence" be based on anything but the sum of each individual intelligence? Imagine this:

    100 + 100 + 100 = 300. BBC is basically saying something along the lines that 80 + 80 + 80 can still equal 300. Individual intelligence is "collective" intelligence, period.

    Also, notice the tropes: "collective intelligence", "gender ratio", "cultural stereotypes"(the nature vs nurture debate is still going on, but everyone involved acknowledges both factors are important).

    Who are these people who made these alleged breakthroughs in neuroengineering? Any names? Mind actually describing the methodology of these experiments please?

    Why would I want to have my own emotions, memories, and thoughts liable to be hacked by someone and used as blackmail? Will authorities require all thoughts be publicly available to catch potential terrorists and criminals "for your own safety"? When people inevitably start using this telepathy to send things like porn and bomb-making instructions to each other, are police going to literally arrest people for thoughtcrime?

    Do not believe any of this horrific propaganda.

    What if, iq is going down because we are importing millions of people from countries with sub 100iqs?

    Some places have iqs of 75. Thats clinically r3t4rd3d

Cyber Attack: Ransomware causing chaos globally – BBC News

Published

on



Tens of thousands of organisations have been caught out by a computer virus called WannaCry. The malicious software locks data away and demands a payment of up to $300 (£230) a time before it will restore scrambled files. In the UK, many hospitals fell victim and some health organisations diverted ambulances and cancelled non-essential services as they sought to contain and clean up the infection. Infections in more than 99 nations are being reported by security firms. It appears that the hardest hit are Russia and Spain.

Is this AI’s moment of truth? | BBC News

Published

on



A year ago, artificial intelligence was being sold as something close to science fiction — a technology that could transform society, cure disease, even reshape the global economy.

Today, the tone is changing. The companies leading the revolution are racing to the stock market — chasing billions in investment — while quietly confronting a much harder reality: AI is expensive, unpredictable, and far from profitable.

At the same time, some of the very people building this technology are warning we may be going too fast — even calling for a global pause.
And beyond Silicon Valley, a different story is emerging: growing public anxiety, political backlash, and the rise of what some are calling anti-AI populism.

So is AI entering its most pivotal moment yet — caught between financial pressure, technological risk, and political resistance?

AI Decoded Presenter Christian Fraser is joined by Financial Times AI Editor Madhumita Murgia, Thematic Strategist at Deutsche Bank Research Adrian Cox and Richard Coffin, Host of popular investing podcast ‘ The Plain Bagel’.
