I don't think it's just you noticing a difference—but the improvement likely isn't coming from the CAPS LOCK itself.

Here's what's probably happening:

**Why it might *seem* better:**
- You're being more deliberate and specific when you write in caps, which naturally makes prompts clearer
- Caps demand more attention, so you might be reformulating questions more carefully
- It's more noticeable when you get good results after doing something different, creating a memorable contrast

**Why it's not the caps:**
- AI systems like Claude don't "hear" tone or interpret caps as shouting in a way that changes intelligence
- Caps can actually introduce slight parsing quirks (though minimal)
- Consistency matters more than formatting—a clear lowercase question beats a rambling caps lock rant

**What actually improves outputs:**
- Being specific about what you want
- Providing context
- Asking follow-up questions
- Using clear structure in your prompt

If caps is making you *write* better questions, then yes—you'll see better results. But the mechanism is your improved clarity, not the formatting itself.

Try the same carefully-written question in lowercase and you should get essentially the same quality output.
