Is there a way to increase and decrease chances of being reincarnated?
You pose an interesting question. I suppose an equally challenging question would be, "If reincarnation exists, why wouldn't it exist for everyone?". Why would the cause of death affect whether one is reincarnated or not? There is a concept among some believers, that reincarnation is meant only for those whose lifetimes were left unfulfilled because of accident, murder, or some kind of disaster which prevented individuals from fulfilling their purpose in life.
However, we draw much of our evidence for reincarnation from more than just reasoning and logic. The anecdotal evidence of those who claim personal memories and experience, for example, is often considered adequate—especially if such memories correspond with each other, and if such memories contain information that could not have been known by any other means. And if such memories involve all manner of deaths, then the theory that only deaths from accident, murder or disaster bring about reincarnation may be weakened.
Another reason that people tend to accept reincarnation for everyone has to do with their instinctive need for justice and equanimity. Or, perhaps, it has to do with the innate wisdom that one life, alone, is not enough to give one's life purpose. For, if there is purpose to anything, it is believed that life must have some purpose, if nothing else.
