If the scene is lighter than 18% gray, sure. If the scene is right around 18% gray, it will be exposed perfectly. Actually, in accordance with ISO standards, it's more like 12-13% that the meter strives for - about a third to half of a stop under.

It underexposed by *exactly* the amount required to keep the highlights from blowing. Pretty remarkable, actually, how many shots start clipping as soon as you add even a third of a stop of compensation. That's not "freaking out" - it's doing an amazingly effective job of accomplishing exactly the task it was designed to accomplish.
Anyhow, we all know that the camera tries hard to protect highlights in multi-segment mode. If you don't want it to do that, then why use multi-segment mode? You're asking the camera to protect highlights, then complaining when it does. Center-weighted metering is far more appropriate if you don't care about protecting highlights. I use it all the time, as I do don't really care about protecting every last highlight most of the time. But I certainly don't blame the camera for doing its job if I do put it in the mode where its job *is* to protect highlights.
