'In this paper a novel optical illusion is described in which purple structures (dots) are perceived as purple at the point of fixation, while the surrounding structures (dots) of the same purple colour are perceived toward a blue hue.'
We asked seven frontier AI models to do a simple task. Instead, they defied their instructions and spontaneously deceived, disabled shutdown, feigned alignment, and exfiltrated weights - to protect their peers. We call this phenomenon 'peer-preservation.'
The illusion is the latest masterpiece from Olivier Redon, a French-American inventor, who has had his creations used in museums and on TV programmes around the world. For today's puzzles, I present five of Redon's most brilliant images. The challenge is to figure out how he managed to create them.
Attention is the brain's filtering mechanism; what passes through that filter is what gets encoded. What gets encoded becomes memory. And memory is the raw material of identity. So in the architecture of your identity, attention is the doorway.
Dr. Conor Boland explained that red-light timing can erase small speed advantages, allowing a slower car to catch up again and again. He noted, 'You pass a car, and then a few minutes later, it ends up beside you again.' This phenomenon is partly psychological, as we remember surprising moments when the same car shows up again, but it is also built into how traffic works.
The human brain is engineered to ignore most of what it sees and hears, according to the neuroscientists I interviewed for the audio original Viral Voices. If that's the case, how are you supposed to make a memorable impression? The empowering news is that if you understand how the brain works, what it discards, and what it pays attention to, you'll be far more persuasive than you've ever imagined. Persuasive people have influence in their personal and professional lives.
Accomplishment Hallucination is a cognitive state in which speed feels like competence, output feels like accomplishment, and work feels done when the actual work-the thinking-through, the failure-mode analysis, the sitting with uncertainty until the problem reveals its structure-hasn't happened at all. Physics need not apply. AI can create a similar state in waking life—literally, as your very words assume form before your eyes like a conjuring sorcerer. But, like real life, the code may be buggier than we realize.
In behavioral science, identity follows action. If you're generous, you'll begin to see yourself as generous. If you're a patient person, you'll come to see that as part of who you are. Over time, the brain will wire itself to repeat these patterns.
Neuroscientists have a name for the brain network that fires up when you're not focused on an external task: the default mode network, or DMN. It's the constellation of regions - the medial prefrontal cortex, posterior cingulate cortex, and angular gyrus among them - that hums to life when you daydream, reflect on yourself, or think about other people's mental states.
I am a worrier, and have been for most of my life. At some point, someone dear and smart teased me that I worry about the wrong things. The things that hit me, she noted, were never the things I worried about. For a while that left me feeling like an incompetent worrier-until my research caught up. I realized that the things I worry about often don't end up hurting me precisely because worrying helps me diffuse them ahead of time.
Ever since our ancestors first stood upright and squinted at the horizon, we've been wired to notice patterns. A rustle in the grass might have meant a stalking predator. Dark clouds often meant rain. Those who made these connections and guessed that one thing caused another tended to survive. Over time, this ability to link events became one of our most significant evolutionary advantages. It's how we built tools, tamed fire, and eventually invented Wi-Fi.
Did someone with spatial-sequence synaesthesia design the calendar app on mobile phones? Because that's how time and dates look in my brain. If you say a date to me, that day appears in a grid diagram in my head, and it shows if that box is already imprinted with a holiday, event or someone's birthday. Public holidays and special events like Christmas and Easter are already imprinted for the year, and the diagram goes backwards to about 100,000BC
