Irony of Information
The only people who know the dangerous truth about Jurassic Park are the people trapped within it, who must survive and escape. However the dangerous truth about the park (the out-of-control dinosaurs) is the same factor that restricts their opportunities for escape.
Irony of Power
Human beings, and powerful scientists in particular, create a form of life that later escapes their control. The dinosaurs actually kill and eat some of the engineers and scientists responsible for their creation.
Irony of Knowledge
Human beings often don't realize just how ignorant they are. Ian Malcolm illustrates this phenomenon when he resets the InGen computers to look for more animals than are expected. This, together with his graph showing the measured heights of a particular kind of dinosaur, provide evidence that the animals have escaped and have been reproducing independently for quite some time.
Irony of Power Protectiveness
The wealthy, elderly billionaire visionary and investor John Hammond invites his grandchildren to Isla Nublar to enjoy a behind-the-scenes vacation as Evie Sattler, Alan Grant, Ian Malcolm, and the lawyer Donald Gennaro review the island to reassure the other investors as to whether it is safe. By doing so, John places his grandchildren at risk. He allows other people to take the risks involved in saving the children, going outside only after he believes it is safe to do so. In the process, he accidentally breaks his ankle and is killed and devoured by a group of Procompsognathus, the smallest and most innocent of the park's dinosaur residents. This inversion of power-- an extremely powerful human being killed and eaten by tiny dinosaurs-- is both ironic and hilarious. The wealthy, powerful John Hammond, so anxious to protect his grandchildren and his financial interests, ends up being unable to protect himself from being nibbled to death.
Irony of Technology
With all its technology, InGen and its scientists are completely unable to prevent the lifeforms they create, clone, and breed from breaking free of their control. The entire novel is a gigantic "neener, neener" from the dinosaurs to the supposedly superior humans.
Irony of Class
Robert Muldoon, the game warden, has a realistic and unromantic view of dinosaurs. He survives, while the much better educated Dennis Nedry, John Arnold, and lawyer Donald Gennaro die messily. He wedges himself into a drain, so that the velociraptors cannot attack directly, and waits for an opportunity to escape.
Irony of Interest
The billionaire investor John Hammond invites Dr. Grant, Evie Sattler, and Ian Malcom to Isla Nublar to see the new theme park, "Jurassic Park", before it opens. He also brings his lawyer, Donald Gennaro. Hammond's goal is to solicit endorsement from the scientists and the mathematician in order to reassure investors. Perversely, after seeing the park and the science that made it possible, the scientists and mathematician declare the park unsafe. The only one who endorses Hammond's vision is Donald Gennaro, who is completely seduced by the amount of money to be made by the finished park. Thus, the person whose financial and professional interests most strongly recommended a conservative course of action ended up being the only person who endorsed the project.
