Schützt Gehirnjogging vor Demenz? Was wirklich hilft
Schützt Gehirnjogging vor Demenz? Kaum: Rätsel trainieren nur sich selbst. Was kognitive Reserve wirklich aufbaut, von breitem Lernen bis Bewegung.
Warum Tech-Eliten ihre Kinder von Bildschirmen fernhalten
Lassen Tech-CEOs ihre Kinder ans iPad? Auffällig selten: Was sie schützen, ist der Aufbau von Konzentration und Verknüpfung, und das ist übertragbar.
Raus aus der Tutorial-Hölle: vom Zuschauen zum Können
Aus der Tutorial-Hölle entkommst du, indem du aufhörst zu konsumieren und anfängst zu bauen. Warum Zuschauen Können vortäuscht und die Reibung das Lernen ist.
Bestes Team-Wiki? Warum euer Notion im Chaos versinkt
Das beste Team-Wiki ist keine Tool-Frage: Euer Notion versinkt im Chaos, weil 50 Denkstrukturen in eine Hierarchie gepresst werden. Diese Regeln retten es.
Linke und rechte Gehirnhälfte verbinden: Mythos und Fakten
Linke und rechte Gehirnhälfte verbinden? Beide arbeiten über den Balken längst zusammen. Was der Mythos verspricht und was dem Denken wirklich hilft.
Kann die Polizei meine Notion-Notizen beschlagnahmen?
Kann die Polizei Cloud-Notizen beschlagnahmen? Ja, mit Anordnung. Dein Gedächtnis nicht: Warum das erste Gehirn der einzige wirklich private Speicher ist.
AI offloads reasoning, not just memory
Calculators offloaded computation, GPS navigation, writing memory. AI is the first tool to offload reasoning itself, which is different in kind.
Does becoming ambidextrous make you smarter?
Adult hand-switching is motor learning, not a brain upgrade. The corpus callosum is real, but the bridging that matters is connecting ideas, not hands.
Caffeine limits: why more focus is not more insight
Caffeine sharpens focused, convergent work but narrows the associative thinking insight needs. Past a dose, it locks the mind into linear tracks.
Claude Fable 5 vs GPT-5.5: which is better?
No clean overall winner: Fable 5 leads Anthropic's benchmarks, GPT-5.5 is cheaper at $5/$30 vs $10/$50, both have 1M context. Test on your own task.
Cognitive augmentation starts with your biology
Every tool amplifies the mind it is attached to. Real augmentation builds a connected internal structure first, then adds the AI and the hardware.
What If the Internet Went Down Forever? Think Locally
What to do if the internet goes down forever? The real risk is not lost files but a mind that cannot think without the cloud. Build the knowledge into yourself.
Cyborg vs Centaur: how to work with AI
Three ways to work with AI, and the research favors one. A 2026 study of 244 consultants found Centaurs, just 14%, hit the highest accuracy.
Divination, decoded: random input for new ideas
Tarot and the I Ching work as thinking tools, not prediction: a random prompt breaks fixation and forces you to synthesize a new perspective.
Is Voice Journaling Effective? Escaping Your Own Echo
Is voice journaling effective? It can be, but spoken venting loops your own biases. It works when you force yourself to map the contradictory case aloud.
How Does Vision Pro Eye Tracking Work? Gaze as Input
How does Vision Pro eye tracking work? Infrared cameras map where you look, and the gaze becomes the cursor. A controllable interface needs a controllable mind.
Fasting for neurogenesis: what BDNF actually does
Fasting raises BDNF and growth chemistry tied to new neural connections. It improves the substrate, but it does not build knowledge on its own.
How Thought-to-Text Actually Feels: Formatting the Mind
Thought-to-text does not feel like telepathy. It feels like formatting: breaking a vague feeling into discrete nodes a brain interface can actually read.
What GLP-1 drugs do to motivation and reward
GLP-1 drugs act on the dopamine reward system, not just appetite. If cheap thrills fade, the motivation left has to come from structural synthesis.
HRV and cognitive flexibility: what the link means
Higher HRV tracks with flexible thinking through shared prefrontal-vagal circuitry. It is a marker of readiness, not a switch for synthesis.
How do I access Claude Fable 5?
Claude Fable 5 is on the API (claude-fable-5) and claude.ai now; paid plans are phased. Bedrock, Vertex, and Copilot are unconfirmed; Mythos 5 is not public.
How to stop hoarding notes and start synthesizing
Stop hoarding notes by redefining a note as a claim you can defend and connect. Capture less, process to claims, link on the way in, write on a schedule.
What Nick Land's philosophy means for enhancement
Land's accelerationism reads the urge to enhance as a systemic pull, not a free choice. The disciplined response is to strengthen your substrate first.
How much does Claude Fable 5 cost?
Claude Fable 5 is $10 per million input tokens and $50 output, double Opus 4.8. 1M context at standard rates; Batch API halves it; subscriptions are phased.
