<passage>:
to smile ... if he ever laughed at himself, the entire ship and crew were as good as dead! If there is anything I am afraid of, and there probably is, it is having a rookie Accident Prone, half-starved from the unemployment lines, aboard my spaceship. They are always so anxious to please. They has a very low life expectancy on Earth due to the automobiles they are The Admiralty, however, is a very thorough group of men. Before they open a planet to colonization or even fraternization, they insist on knowing just what they are up against. Accident Prones can find out what is wrong with a planet as easily as falling off a log, which they will if there is one lonely tree on If an alien race will smile patronizingly on your heroic attempts at genocide, but be offended into a murderous religious frenzy if you blow your nose, you can take the long end of the odds that the Prone will almost immediately catch a cold. Baxter's guard was doubled as soon as we set down, of course, and danger, not the rigidly secured safety. We like it that way. No one knows what causes an accident prone. The big insurance companies on Earth discovered them when they found out in the last part of the nineteenth century that ninety per cent of the accidents were happening to a few per cent of the people. They soon found out that these people were not malingering or trying to defraud anybody they I suppose everything from psychology to extra-sensory perception has been used to explain or explain away prones. I have my own ideas. I think an accident prone is simply a super-genius with a super-doubt of himself. I believe accident prones have a better system of calculation than a infallibly make the right choice in any given situation. Then, because they are incapable of trusting themselves, they do exactly the opposite. I felt a little sorry for Charlie Baxter, but I was Captain of the tomb. Accident Prones have to stay worried and thinking, trying to break out of the jinx that traps them. Usually they come to discover this themselves, but by then, if they are real professionals with a career in the Service, they have framed the right attitude and they keep it. Baxter was a novice and very much of an amateur at the game. He didn't for the position of Prone aboard a spaceship. He had been poor—hungry, cold, wet, poor—and now he had luxury of a kind almost no one had in our era. He was drunk with it, passionately in love with it. It would cease to be quite so important after a few years of regular food, clean clothes and a solid roof to keep out the rain. But right now I knew he would come precariously close to killing to keep it. Or to being killed. "Where is Baxter?" I asked the hulking guard. My eyes were on the sofa. this, much less Baxter's bed in the next cabin. But then I am only a me. There wasn't a thing wrong with the plumbing, so Baxter must have were missing. Baxter had left the spaceship and gone off into an alien Charlie Baxter had less. Lots of things can change on a planet in fifty were Baxter, Elliot and Sidney in the middle of a curious mob of aliens. Charlie Baxter had got pretty thin on his starvation diet back on have anything to worry about, that the precious Accident Prone would behavior in the report. Naturally, that meant by now he had discovered the fatal error. Baxter swallowed and started forward to meet the alien halfway. His "We do not understand," the native repeated. "Do you hold us in so much contempt as to claim all of us as your brothers?" a mistake and later I wanted to be sure I knew just what it was. Frankly, I would have used the blood-brother gambit myself. I had also read about it in the survey report, as I made a point of telling you. This just proves that Accident Prones haven't secured the franchise on mistakes. The difference is that I would have gone about it a lot more cautiously. "Enough of this," the native said sharply. "Do you claim to be The other aliens didn't try to get to Baxter, but when they saw Elliot was my turn to grind his face in the muck. I had a nice little problem to contend with. I knew the reason Baxter had slipped out at night to be the first to greet the aliens. He was determined to be useful and necessary without before in his life, but at the same time it hurt him to think that he was valuable only because he was a misfit. that would be as good proof of conditions as if he made the mistakes he was supposed to do. But he couldn't lick that doubt of himself that had approach, but Charlie would probably lose all self-confidence and sink down into accepting himself as an Accident Prone, a purely passive state. Baxter, his two guards and the native spokesman. The idea that seemed to be in favor was the survival of the fittest. particularly cunning, the runts of the litter did not survive the first year and rarely more than one sibling ever saw adulthood. Obviously, to claim to be a native's brother was to challenge him to a Charlie Baxter's original mistake had supplied us with the Rosetta while you lay there, haven't you, Baxter?" "Yes, sir. I see I've been fighting this thing too hard. I am an Accident Prone and I might as well accept it. Why not? I seem to always muddle through some way, like out there in the jungle, so why should I worry or feel embarrassed ? developing a certain amount of doomed self-confidence, but they couldn't be allowed to believe they were infallible Prones. A Prone's value lies in his active and constructive effort to do the right thing. If he merely accepts being a Prone, his accidents gain us nothing. We can't profit from mistakes that come about from resignation or laughing off blunders or, as in this case, conviction that he never got himself into anything he couldn't get himself out of. "I have some facts of life to give you, Baxter," I told him. "It actively fulfill your position. You have to make He sat down on the edge of the bed and examined the pattern in the carpet. "Not exactly, sir. But I get tired of people waiting for me to make a fool out of myself. I have a natural talent for—for Creative Negativism . That's it. And I should be able to exercise my talent with dignity ." I snorted. "It takes skill and training, Baxter. Your papers entitle Pile Driver, j.g. It keeps getting harder and harder to recruit an APD, j.g. I suppose it's those reports about the eventual fatalities due to Baxter looked back at me steadily. "There are a lot of rumors about the high mortality rate among Accident Prones in space, too." He was right. We had started the rumors. We wanted the Prones alert, active and scheming to stay alive. More beneficial accidents that way. Actually, most Prones died of old age in space, which is more than "Look here, Baxter, do you like your quarters on this ship?" I demanded. "But there I would have some chance of advancement . I don't want to be stuck in the rank of Accident Prone for life." I stared at him in frank amazement. "Baxter, the only rank getting poisoning?" Baxter's jaw thrust forward. "It must be pretty bad—but it isn't as violent as being eaten by floating fungi or being swallowed in an earthquake on some airless satellite." "No," I agreed, "it is much slower than any of those. It is unfortunate that we don't carry the necessary supplies to take care of Pile accidents to be denied the supplies in that Kit, I should think. Of I barely halted a groan. He thought I resented him and was deliberately holding him down into the miserable overpaid, overfed job that was beneath him and the talents that so fitted him for the job.
