Baking soda is sodium bicarbonate. Same substance, two names. One is a precise descriptor that tells you what the thing is and how it behaves. The other is a kitchen nickname that tells you where you last saw it. Almost nobody reaches for the precise one, because the nickname is easier and it works, right up until it doesn't.

This is how a convenient abstraction eclipses a reality. Baking soda is a label optimized for a single context. It carries no reminder that the same compound buffers pool water, kills odors, puts out grease fires, and reacts with acid on contact. The nickname narrows the thing down to one use and then quietly stands in for the whole.

The cost is invisible when the stakes are low. If you only ever bake, calling it baking soda loses you nothing. But the habit, letting the familiar name replace the actual thing, is not confined to the pantry. We do it with risk, with traffic, with engagement, with any term that started as shorthand for something specific and hardened into a word we no longer look behind.

The danger isn't the nickname. It's forgetting the nickname was ever a nickname.

So the discipline is simple and unglamorous: every so often, say the precise name out loud. Sodium bicarbonate. Non-human traffic. Unverified impression. Not to sound pedantic, but to keep the referent in view. Because the moment the label fully replaces the substance is the moment you stop being able to reason about the substance at all.
