## Blog posts

- [You Don't Need to Write Separate Speeches for Men and Women](https://julienreszka.com/blog/you-don-t-need-to-write-separate-speeches-for-men-and-women/index.md): Conventional wisdom says a persuasive message can only move half a room. Research on fear appeals found the exact combination that moves everyone instead.
- [You're Likely Working Too Much](https://julienreszka.com/blog/you-re-likely-working-too-much/index.md): Elon Musk calls 100 hours a week versus 50 simple math: twice the time, twice the output. The one dataset built to test that claim found close to nothing.
- [Singapore's Neuron Rack Costs More to Rent Than It Saves](https://julienreszka.com/blog/singapore-s-neuron-rack-costs-more-to-rent-than-it-saves/index.md): Singapore's neuron-powered server cuts the power bill by 99 percent. Renting that capacity costs 2.8 times what the power saves, per Cortical Labs' own pricing.
- [It's Not Time to Build](https://julienreszka.com/blog/it-s-not-time-to-build/index.md): Manufacturing is the least profitable stage of the value chain. Building only pays off when it starts from a real UX insight and ends in something sellable.
- [Who Can Afford a Bad Reputation?](https://julienreszka.com/blog/who-can-afford-a-bad-reputation/index.md): A Yelp study found a one-star swing moved revenue 5 to 9 percent for independent businesses, and nothing for chains. Reputation costs what you cannot replace.
- [You Underestimate How Much People Want to Hear From You](https://julienreszka.com/blog/you-underestimate-how-much-people-want-to-hear-from-you/index.md): A replication found recipients rate an unprompted text as more appreciated than senders expect. The gap is not caring less, it is not knowing what to say.
- [If I Could Only Do One Exercise, It Would Be Squats](https://julienreszka.com/blog/if-i-could-only-do-one-exercise-it-would-be-squats/index.md): Squats train the exact movement most predictive of staying functionally independent later in life, and they help protect muscle mass while eating less.
- [Why and How I Skip Lunch](https://julienreszka.com/blog/why-and-how-i-skip-lunch/index.md): I eat two meals a day: eggs in the morning, soup at night, nothing in between. Here is the actual research behind each choice, caveats included.
- [Job Ads Tell You What Employers Want, Not What You Want.](https://julienreszka.com/blog/job-ads-tell-you-what-employers-want-not-what-you-want/index.md): Job postings rarely disclose real pay, flexibility, or stability. That information exists, spread across sources nobody has time to check.
- [Your 200-View Tutorial Might Work Better Than You Think](https://julienreszka.com/blog/your-200-view-tutorial-might-work-better-than-you-think/index.md): AI Overviews cut average clicks by 61 percent. Brands they cite by name saw clicks rise 35 percent instead. Being named is the real metric.
