Yesterday's comic was, of course, in reference to Twyman's Law.
Applicable not only to experiment analysis, but also life. If it looks too good to be true, then it probably is 😅

Your PM: "What happened with that experiment?"
You: Opens 17 tabs, 3 spreadsheets, and a Slack thread
Sound familiar? We fixed that.
Introducing Experiment Dashboards in GrowthBook 4.1:
✅ Create custom views
✅ Highlight metrics
✅ Add context
✅ Share a single link instead of a dissertation

It's a hard truth—but we're not all SQL geniuses.
Get a little (or lot of help) with your next query by using our new natural language to SQL generation feature. Ask, for example, to list the top 10 pages by view count in the past 3 months and get back a crisp SELECT statement.
See Graham's demo

Teams often struggle with an ever-growing list of metrics, ballooning from 20 to 200. Finding a specific metric during a new experiment can be tough, leading to even more creation ☠️. AI can automatically summarize metrics, making them easier to find and preventing duplicates. Watch Graham's demo 👇

Hypothesis enforcement just dropped ✨
No, you won't get a ticket for sloppy hypotheses—but this AI-powered feature ensures your team writes them right.
YOU set the quality bar. Academic rigor or lighter touch, your choice.
Don't just run experiments, run them right.

Like an erstwhile PSA: "Do you know where your feature flags are?" As part of our 4.0 launch, we shipped feature flag usage analytics, which means that for every feature flag, you now know:
🛎️ How often it's been evaluated
💁 Which values are being served
📏 Which rules are being hit
🌈 And more

Have you run into this annoyance? You're in your experimentation tool but you have to jump into Looker or Mode just to write some quick SQL to answer a simple data question.
All of that context switching adds up, which is why we built SQL Explorer right into GrowthBook #abtesting #datascience

Hot take: The most underrated developer skill in 2025 isn't AI prompting or the latest framework.
It's the ability to ship code you're not 100% confident in.
Feature flags teach you to embrace uncertainty and let data decide. This mindset shift is worth more than any bootcamp.
