Does Active SETI Put Earth in Danger? 647
Ponca City, We Love You writes "There is an interesting story in Seed Magazine on active SETI — sending out signals to try to contact other civilizations in nearby star systems. Alexander Zaitsev, Chief Scientist at the Russian Academy of Sciences' Institute of Radio Engineering and Electronics, has access to one of the most powerful radio transmitters on Earth and has already sent several messages to nearby, sun-like stars. But some scientists think that Zaitsev is not only acting out of turn by independently speaking for everyone on the entire planet but believe there are possible dangers we may unleash by announcing ourselves to the unknown darkness. This ground has been explored before in countless works of science fiction most notably "The Killing Star," a 1995 novel that paints a frightening picture of interstellar civilizations exterminating their neighbors with relativistic bombardments, not from malice, but simply because it is the most logical action."

Which probably could explain why aliens might be more pacific than us.
What I'm basically saying, is that "peace" is a prerequisite for achieving "space age",
because "space age" comes only far later after "big weapons" in the technological development,
and without "peace", a civilisation may blow it's entire planet at the "big weapons" stage, long before being able to achieve "space age".
Just look at our history :
As you said, our own worst enemy has always been ourself : the other humans against which we engage war.
Specially in recent history, we've reached the point where some population have enough warfar technology and power that they might oblitared the whole planet if weapon escalation runs out of control.
Nuclear stockpiling and M.A.D. programs are the epitome of this situation.
MAD fundamental premise is that nobody will attack because everyone dies in the process of retaliation that follows (except maybe a bunch of politician hiding into caves with lots of young pretty nubile girls, isn't it, Dr Strangelove ?)
MAD seeks to make atomic war an unaffordable option because of too high cost.
The implicit consequence is that if someone played fool anyway, we WILL all definitely stop existing.
And at the same time, we haven't even reached true space travel yet, and we're very far from being able to do it on a large scale. We can only plant a couple of flags on our moon, and send two motorized webcams to the directly neighbouring planet.
An alien race that is able to detect us AND come toward earth to meet us, must necessarily be extremely advance, far beyond the point at which we are now. Which would possibly mean also having gone through a long story of dangerous technology (military and such).
If that alien race wasn't deeply motivated to be peaceful, they'll have had a lot of opportunity of blowing themselves up with all discovery they had the time to make before achieving space exploration.
Only a race that repress its tendency to kill everything can survive technology.
Even we as human have a small tendency to try to refrain of causing too much destruction.
In antiquity, pillaging and burning down to grounds enemy cities has been standard military practice, even told in classical literature.
In the middle ages, having a lot of deaths during wars was considered pretty normal.
As history progressed more dangerous technology has become available, people start being reluctant using it. Moral value change.
MAD was a pissing context without (hopefully) any real intent to engage all those nukes.
Even if atrocities are comited during modern conflict, those are much more criticized by the public (see current opinion about Irak or the various massacres and ethnic cleansing happening under dictatorship).
Slowly we are discovering that hurting each other may not be the best procedure.
A lot of the "modern" forms of conflict have moved to much more political and commercial ground. Emerging country don't long anymore to conquest foreign land, only to capture their markets.
Thus maybe, we ourselves will be able to survive until space age without blowing ourselves up with all military technology we may invent in the process.
But probably, the first alien race that will meet us will probably be peaceful because other wise, by then, they won't exist anymore.

This is pure fallacy, although I appreciate that you used the word "likely" rather than speaking in absolutes. Generally, good education comes in peace time. Sharing of ideas comes from openness and trade with other tribes/cultures. Rockets are probably based on fireworks (and aerodynamics), which are based on so-called gunpowder -- something that was not used destructively for for many years after its creation. Radar came about in war, yes, but all of the technology leading up to it was developed in peacetime. That the first need to make the next leap came about because of war is irrelevant; the technology was there, the progress was ready to be made, and if the technique was needed, someone would have made that leap.
As someone once said, "the tradegy of war is that it uses man's best to do man's worst". War is destructive, not creative. Those involved in war often claim credit for things either through delusion, or power. That does not mean that the warlike people, warlike ideals, or even warlike circumstances are the reasons such things exist. I'm sure da vinci would've preferred to work on less lethal things, if less lethal people had held the money and power.

Granted, interstellar distances are a perfect defense against anyone near technological parity with us, but why would we assume that an alien civilization has advanced no further than that?
Furthermore, some people maintain the (preposterous) belief that any race that is substantially more technically advanced than us would, somehow, have to be peaceful and beneficient. However, if they followed a developmental path anything at all like ours, they got that advanced by being anything but peaceable! Where did many of the historical discontinuities in our scientific and technical knowledge come from? Why, from the tremendous R&D investment the world's militaries command in times of war.
