In Fourth Iteration: Control (III), Harding explains why Malcolm's fall from the tyrannosaur's jaws did more damage to him than the bite itself. Through this conversation about the irony of the situation, the novel advances the ethos of both Malcolm and the tyrannosaur in service of its message about the hubris of corporate science:

Harding said, “....[W]ith a small creature like Dr. Malcolm, the animal would just shake him, and then toss him.”

“I’m afraid that’s right,” Malcolm said. “I doubt I’d have survived, except the big chap’s heart wasn’t in it. To tell the truth, he struck me as a rather clumsy attacker of anything less than an automobile or a small apartment building.”

“You think he attacked halfheartedly?”

“It pains me to say it,” Malcolm said, “but I don’t honestly feel I had his full attention. He had mine, of course. But, then, he weighs eight tons. I don’t.”

At first, the revelation that the tyrannosaur's bite is survivable seems to diminish its status as the most fearsome predator any of the humans have ever faced. If Malcolm can survive this surprise encounter, maybe tyrannosaurs are no worse than other modern predators, like lions, that humans keep in zoos. Lions might be dangerous, but humans have learned how to coexist with them while maintaining the upper hand. Humans might be able to do the same with tyrannosaurs. A zoo accident here or there would be nothing new, and it certainly would not threaten the human species. Clearly, some such accidents are even survivable. Malcolm, who has been consistently worried about Jurassic Park as an existential threat to human life, should be heartened by his own survival. 

However, as Harding explains, Malcolm is probably not alive because humans can truly stand up to tyrannosaurs. The tyrannosaur's jaws were never what made it an apex predator. Instead, its immense strength comes from its neck. Its teeth allow it to grip its prey, which it then kills by shaking its head with such force that the prey is torn to shreds. Ironically, what saved Malcolm was his relatively small size compared to the tyrannosaur. Malcolm suggests that the tyrannosaur is a "clumsy attacker" when it comes to prey as small as humans, but he also wagers that the tyrannosaur could easily have killed him if it had tried. Should humans ever capture the "full attention" of this predator, the result would be far worse than a lion attack.

Malcolm and Harding's exchange helps the reader see the tyrannosaur as the existential threat it is. Furthermore, by acknowledging how tiny and insignificant he is compared to his attacker, Malcolm demonstrates humility and perspective that the park's founders consistently fail to show. Malcolm often serves as the book's mouthpiece, giving voice to Crichton's critiques of science that is mixed up with corporate money. These critiques can come off as arrogant, as though Malcolm wants Jurassic Park to fail so that he can be right. However, this scene demonstrates the difference between arrogance and expertise. Malcolm knows what he is talking about with regard to Chaos Theory, and he is realistic about the limitations of his own knowledge and power. He admits when he is out of his depth. By demonstrating the humility that is lacking from Hammond and Wu's god complex, Malcolm wins the reader over to his side.
