There's two ways to look at this.
Traditionally, "the best laid plans of mice and men often go arwy" isn't mathematically modelable (at least I hope not). If the likelihood of my stove breaking, or car breaking, or comb breaking increases simply because I've tried to plan a nice date with my girlfriend.... that's a mighty intuitive universe.
But let's assume that likelihood does go up. "As the desire of the human creature is brought to bear to bring about a modification of his environment the statistical possibility of mishap or breakage increases." This, of course, is expressed by Murphy's Number, a unitless quantity that fundamentally expresses the ratio of likelihood to succeed vs. likelihood to fail and is most often expressed as "1.67221309241 to 1 against."1
Should this be the case, the culture of the peoples of Sod would be the most natural organizers and planners in the universe. Indeed, Rube Goldberg would not have been a writer of comics on Sod — he would have been their lead scientist and hailed as a genius, the veritable savior of their world.
On the other hand, if we look at "if something can go wrong, it will" as the world of Sod experiencing a significantly greater tendency toward Entropy than other worlds, then we have a more manageable law (and we don't have to jump through as many hoops to get to first base). In this case, it's harder to create heat differentials, shear stress, etc. The breaking point of things is much lower than anywhere else in the universe. Worse, the likelihood of breakage also increases, meaning the smallest flaw in manufacturing has a greater chance of leading to failure than elsewhere.
Should this be the case, the Sodians would become the greatest quality analysis people in the universe, as well as masters of redundancy.
1 Scientists have been arguing for centuries about whether or not to use the word "against." However, in a famous experiment by Amarillo Slim (and despite his penchant for poker), he proved that given his desire to win ten games of craps in a row, the universe was decidedly against him.
