The Version 4.4 chapter in Jurassic Park is widely misinterpreted/misremembered, and that particular quote isn't from the book as far as I remember.
The whole point of the chapter was that Wu wanted to make the dinosaurs conform to what the public expected to see - make them slow, lumbering, dumb - as they'd already made safety-related hormonal and genetic manipulations to stop the dinosaurs breeding, and to kill them off if they were deprived of InGen-sourced food. But Hammond wanted authentic dinosaurs so that's more or less what they got.
