The ID research program is contradictory because it seeks evidence of the immaterial in the material. Under what circumstances do they imagine that the immaterial can have an effect on the material?
Whatever form such evidence might take, their list of research papers tells us they're convinced that evidence is well hidden. They're mostly looking at the very tiny in microbiological processes, and at the very far away in stars and exoplanets. They're apparently convinced that whatever the designer is doing, it won't be found in anything obvious like earthquakes, volcanoes, weather, comets, asteroids, medicine, politics, wars, technology, financial systems or social movements.
Since their research is notable for its exclusive focus on the material, obviously they're doing what creationists have always done: seeking the unexplained, deeming it unexplainable, then declaring, "Here be God!" Oops, I mean, "Here be the designer!"
