[Arnold's] all right. He's an engineer. Wu's the same. They're both technicians. They don't have intelligence. They have what I call "thintelligence." They see the immediate situation. They think narrowly and they call it "being focused." They don't see the surround. They don't see the consequences.
Malcolm says this to Sattler in the chapter, "Aviary." "Thintelligence" is Malcolm's term for the type of scientific thinking that he views as responsible for the creation of a disaster such as Jurassic Park. He believes that science is increasingly headed into theoretical realms of concepts and figures that are so large that they are literally incomprehensible to the human mind. Malcolm contends that merely because humankind possesses a tool—a powerful computer that can accomplish feats of bioengineering, for instance—do does not mean that we should use that tool, especially if our knowledge of the tool's precise capabilities are so limited. We see this limited view in Arnold and Wu, who fail to foresee the consequences of their research and actions but go ahead and do it anyway, merely because they can.
