And there's another likely selection bias in that any solar system with a hot Jupiter isn't going to have inner planets.Hot jupiters are a classic example of selection bias. They are relatively common because they are easiest to find.
The assumption before exoplanet observation was that our solar system was typical, and even with our limited data, it's pretty clear that this is not the situation.
The planetary people that I know of strongly disagree with that. If you have Jupiter mass objects in the inner solar system then the inner solar system becomes wildly dynamically unstable. It turns out that one reason that objects in our solar system are relatively "well behaved" is that Jupiter and Saturn are in a rough resonance that circularizes both their orbits. If you didn't have that resonance then over the course of a billion years, there's really nothing to keep Jupiter from crashing into the inner solar system.Planetary spacing was an 18th century exercise in numerology resulting in the Titius-Bode law.
I know of no particular reason earth orbit could not be substantially different than it is and still be stable.
It turns out that it's very hard to keep N-bodies dynamically stable.
I know people who have at least speculated that Titus-Bode is an application of the anthropic principle. Most solar systems don't have well spaced planets, but solar systems without well spaced planets end up without astronomers.
