Being a Vulcan type won't necessarily make you wealthy. Most commerce is based on the art of selling, not the art of logic. In other words, tricking people. The best products from a technical standpoint often fail in the market. Better and cheaper GUI's than MS-Windows existed in the 80's, but MS's marketing muscle steam-rolled them. If you are talking about "smarts" in terms of inventing new things in the lab, as I mentioned earlier, being right or smart and being logical are not necessarily the same thing. In my book, being logical is being able to produce a clear line of reasoning for a suggested course of action. The "givens" in the "proof" may be wrong, but at least the proof is correct using the stated givens. The debate should then be on the givens, not on the proof logic. For example, my suggested UI designs often make assumptions about what confuses end-users. I often don't have inspectable studies to justify such, and others are welcome to disagree with human UI interaction psychology. But at least my assumptions are clear, and I make a decent attempt to explain the steps user may take or think in based on my experience, such as inconsistencies between screens, or variances from other common products an org uses.
