Lennart Nacke, PhD @lennartnacke.com · 08/09/2026Uncertainty can be fun: In a mystery novel. In live sports. In gambling. AI can make serious decisions feel like harmless conversations. It reassures you calmly. It’s tempting to stop checking. But your stakes haven’t changed. Stay sceptical. 001
Lennart Nacke, PhD @lennartnacke.com · 07/09/2026A longer AI answer can make you more confident in a mistake. Longer explanations raise confidence. They don’t help people catch wrong answers. You read more. You feel surer. But you still need to check its assertion.

You're 15 years into the claim they hear in 5 seconds. Conduct the research they skipped over. Win the decade they booked as teaching. 000
Lennart Nacke, PhD @lennartnacke.com · 06/09/2026Don't build your identity around having the right answer. Build it around the process of choosing one. 000
Lennart Nacke, PhD @lennartnacke.com · 06/09/2026We chase certainty to avoid regretting our decisions. Turn to political promises. Read another paper. Ask AI. Eventually, you must choose based on what you know. It's uneasy. It's awkward. It's uncomfortable. Behind the painful distress lies satisfaction. 100

Lennart Nacke, PhD @lennartnacke.com · 05/09/2026How to turn any published paper into a writing template: 10 minutes. ~600 words. 1 highlighter. 1. Find a best paper in your field. 2. Look for 1 sentence that describes: • Context (C) • Problem (P) • Method (M) • Result (R) • Contribution (K) 3. Get the skeleton and the style. 110
Lennart Nacke, PhD @lennartnacke.com · 02/09/2026Instead of watching one hour of Netflix tonight, watch… NO! Just take the time off and watch/read/do whatever you want.

Lennart Nacke, PhD @lennartnacke.com · 29/08/2026How to build a stellar AI artifact: 1. Do your own research on the topic 2. Gather the output quality criteria 3. Find examples of top benchmarks 4. Understand the artifact's audience 5. Iterate quality criteria to match expectations 6. Create rules based on the new criteria 100
Lennart Nacke, PhD @lennartnacke.com · 29/08/2026Content mass production is killing creativity. AI has made us excellent at producing content. Chattie just lurves to help out. And we gobbled it up. The thing is: You don't understand the sh*t you didn't do. You cared about the artifact. You ignored the process. Two ways to fix this: 110
Lennart Nacke, PhD @lennartnacke.com · 28/08/2026AI lets anyone perform intelligence. That must feel great if you're dumb. But it is so scary when you're smart. Who can you trust when you actually need deep advice? Everyone pretends to be an expert. We debate permissions. While AI builds our new reality. 010
Lennart Nacke, PhD @lennartnacke.com · 28/08/2026Computation has outpaced governance. Everyone is mass-producing output. But was output always the goal? What about process? Wearing an exoskeleton to the gym will let you lift heavy. But will you build muscle? Nope. 110
Lennart Nacke, PhD @lennartnacke.com · 28/08/2026These books are free from AI interferences. Coherent, edited, long-form reasoning. Better training for their models. 100
Lennart Nacke, PhD @lennartnacke.com · 28/08/2026AI development is exponential. Our committees slowly review policies. AIs rapidly ingest entire libraries. And now, AI companies are mass-buying, scanning, and destroying old books. All to gain an edge. The Internet is full of slop. 110
Lennart Nacke, PhD @lennartnacke.com · 28/08/2026Your drafts prove you have the time to write. Time lets you write those drafts. Permission lets you publish them. Grant yourself the second one. 000
Lennart Nacke, PhD @lennartnacke.com · 27/08/2026Research is not coding. Writing is not an algorithm. Research is writing is thinking. Thinking needs creativity. Thinking needs friction. Thinking needs space. You can’t optimize this. 010

Lennart Nacke, PhD @lennartnacke.com · 27/08/2026Richard Feynman once wrote on his blackboard: "What I cannot create, I do not understand." He didn't mean abstract theory.

Lennart Nacke, PhD @lennartnacke.com · 26/08/2026It took a 5 years to master your discipline. It only took 3 anonymous reviewers to bury it. The institution trained you to impress them. Yet, you lack the clarity to feed your work to the world. You write to: • hide behind passive verbs. • cover every edge case. • avoid peer criticism. 110

Lennart Nacke, PhD @lennartnacke.com · 12/08/2026How anyone can get over the fear of criticism (this is what I did): 1. Publish about something you have a real opinion on 2. Collect the criticism that you get 3. Notice how little of it draws blood 4. Compare that sting to another year of keeping your knowledge silent Simple but powerful. 010

Lennart Nacke, PhD @lennartnacke.com · 11/08/2026Your momentum only has 3 bottlenecks: 1. Restart size 2. Restart speed 3. Restart shame At any time, you must shrink one of these (and put every grand comeback plan on a Later list.) Create a smaller first post, get a faster return → zero apologies. 100

Lennart Nacke, PhD @lennartnacke.com · 10/08/2026If the question matters, it has to win a block of time before the day starts performing urgency. 000
Lennart Nacke, PhD @lennartnacke.com · 10/08/2026Most research days fail in a boring way. Not because the idea is weak. Because the first clean hour gets spent on work that feels responsible and leaves nothing behind. A meeting happens. An email gets answered. A form gets filed. The paper does not move. 100
Lennart Nacke, PhD @lennartnacke.com · 10/08/2026They are necessary. They push your ideas past peer review. What looks too polished to the paranoid naked eye often looks like competence to a serious reader. Don’t dumb your prose down to perform humanity. Keep the rigour. Keep the clarity. It's your name on the paper, not Claude's. 020
Lennart Nacke, PhD @lennartnacke.com · 10/08/2026Anyone who says that clear structure means it was written by AI is announcing they don’t read careful research. They don't appreciate the beauty in the mundane. Topic sentences, signposting, and clean abstracts existed long before chatbots came along. 110
Lennart Nacke, PhD @lennartnacke.com · 09/08/2026Clarify the claim in speech first. Lay it bare. The page will stop fighting you. 000
Lennart Nacke, PhD @lennartnacke.com · 09/08/2026Brutal truth: You can’t write the paper you can’t explain out loud. And yes, you can’t explain what you still only sort of understand. When you can't figure out your methods section, it's not a formatting problem. That is your mind telling you the design is still fuzzy. 110
Lennart Nacke, PhD @lennartnacke.com · 09/08/2026Funders, collaborators, students, clients, and journalists do not search your hard drive. They rarely sift through archives. They encounter what you made easy to find. 000
Lennart Nacke, PhD @lennartnacke.com · 09/08/2026Your expertise is already expensive to build. It becomes valuable when someone else can find it in time of need. Papers archive your work for a field. Public writing puts a grip on it. 110
Lennart Nacke, PhD @lennartnacke.com · 08/08/2026One system. Repeated. Simple. Novelty feels like progress. Repetition creates your infrastructure. 000
Lennart Nacke, PhD @lennartnacke.com · 08/08/2026The researchers getting real leverage from AI are not prompting all day. They're running agents. Hermes, Claude, Codex. Boring on purpose. Same literature dig on Monday. Same reviewer pushback script on Wednesday. Same clarity pass before coauthor review on Friday. 100
Lennart Nacke, PhD @lennartnacke.com · 08/08/2026That is not a branding problem. It is a thinking problem. 000
Lennart Nacke, PhD @lennartnacke.com · 08/08/2026Clear writing is not the decoration on top of your research. It is the research, made portable. If colleagues outside your subfield cannot repeat your contribution in one breath, the contribution is still trapped inside your head. It never made its way onto your page. 100
Lennart Nacke, PhD @lennartnacke.com · 07/08/2026Then: rewrite the draft with your standards intact. Fluency is cheap now. A lasting human mark is the whole job. 000
Lennart Nacke, PhD @lennartnacke.com · 07/08/2026AI makes weak thinking sound finished. That is the real danger. A muddy contribution becomes a smooth paragraph. A wild guess puts on a lab coat and boldly walks into territory where no draft has walked before. So invert your workflow. First: make AI attack your argument. 100
