Anyone who’s followed the Jurassic Park and Jurassic World saga has probably run into this curious paradox: people claim they love dinosaurs, yet they protest the moment someone tries to depict them more accurately, often pulling out the old excuse that “they’re all hybrids anyway.” With Jurassic World Rebirth, we’ve seen something unprecedented: a sharp rejection of mutants and hybrids, even though such creatures have been part of previous chapters. This double standard is what makes the paradox so fascinating.
IMPORTANT DISCLAIMER: For me, Jurassic World Rebirth barely scrapes a passing grade. There are interesting ideas, but also many choices that are hard to defend. I’ll discuss this in more detail live with friends from Monster Movie, Jurassic Park Italia, and DiceNDinosaur. But what really inspired me to write this article were the reactions to the film’s creatures and a reel by Sicitalian that, though about Barbie, shows just how much status quo bias shapes our perception of cultural icons. So I asked myself: Does this mechanism apply to dinosaurs, too?
Status quo bias, as defined by Samuelson and Zeckhauser in 1988, refers to people’s tendency to resist change, even when better alternatives exist. It’s not just a matter of habit: it’s a mechanism triggered by fear of risk, cognitive laziness, or emotional attachment. Change demands mental effort, creates uncertainty, and threatens emotional bonds.
When we apply this to dinosaurs on screen, we have to wonder why the status quo bias seems to start specifically with Jurassic Park. Before 1993, depictions of dinosaurs were fragmented and often contradictory: from constantly evolving paleoart to stop-motion films, there wasn’t one dominant visual model audiences felt attached to. Jurassic Park changed the game, offering a spectacular, cohesive vision that reshaped the public imagination. And beyond that, the film’s phenomenal success launched an unprecedented wave of merchandising — toys, models, videogames, illustrated books, theme parks — turning those dinosaurs into global icons and cementing a deep emotional bond. That’s where status quo bias is born: when an image stops being just a representation and becomes part of the personal history and emotional landscape of entire generations.
In theory, audiences say they want dinosaurs. In practice, they want creatures that are recognizable, spectacular, and follow a set script: the T. rex with its iconic roar, the smart, scaly Velociraptor, the frilled, venom-spitting Dilophosaurus, the relentless Spinosaurus. Science, accuracy, updated data, these matter little. What matters is emotion, familiarity, and narrative continuity.
Here we hit the key point: what does the dinosaur represent to the audience, compared to a monster? It’s a figure halfway between reality and legend, real enough to spark scientific wonder, spectacular enough to embody myth. But audiences don’t defend the real dinosaur; they defend their idea of the dinosaur, shaped by pop culture. But apparently, there’s an invisible line beyond which not even the dinosaur-as-myth holds up. A striking example is the (ultimately unfounded) rumor of a fire-breathing T. rex: even fans used to hybrids raised their eyebrows. Had it been true, that feature would have clearly been a narrative gimmick, but for many it would have crossed a line, pushing the franchise too far into outright fantasy… “It’s a dinosaur, not a dragon,” many commented. Yet previous films gave us a T. rex shattering a tree trunk mid-run, a Quetzalcoatlus tearing apart an airplane fuselage, and even a Baryonyx shaking off lava from its head (earning the nickname “Lavaproof Trash”).
Digging deeper, it’s not just status quo bias at work but also the endowment effect (Kahneman, Knetsch & Thaler, 1990), the human tendency to overvalue what we perceive as “ours.” The Jurassic Park dinosaurs aren’t just screen images; they’re part of audience memory, tied to childhood movies, toys, games, posters, collectibles, and online debates. For many fans, “those are my dinosaurs.” So when a more scientifically accurate version or redesign arrives, it’s not judged on its own merits, but it’s seen as a threat to something people emotionally own. It’s not just attachment to the past, it’s symbolic ownership of the past. Any change seems to take something away from that sense of belonging built over decades of pop culture.
Take Velociraptor: in the toys & models world, a scientifically updated version is often sold as “Feathered Velociraptor,” as if that were a variant and not the real form. It’s like selling a “Feathered Ostrich” figure: nonsensical, but seen as necessary to avoid clashing with the entrenched image. Status quo bias makes audiences prefer the familiar cinematic version, ignoring scientific updates, while the endowment effect makes the big, scaly Velociraptor feel like “ours,” something to defend. To emphasize size differences, fans even belittle the real Velociraptor by comparing it to a turkey or quail, when a more fitting analogy would be the harpy eagle, a fierce and dangerous bird of prey. It’s a striking example of how perception outweighs fact, and how hard it is to celebrate one image without tearing down the other.
In 2001’s Jurassic Park III, the gigantic Spinosaurus was seen as an usurper: it killed a T. rex, broke the franchise’s emotional hierarchy, and, lacking any established emotional bond with the audience, triggered disappointment and rejection. A status quo bias resisting a new “king.” By around 2014, things took a twist: while paleontological discoveries gradually reshaped the image of Spinosaurus, fans started to feel nostalgic for the old “Baryonyx with a sail” look (“they nerfed Spinosaurus”). Here, rosy retrospection (Mitchell et al., 1997) kicks in: it’s the mechanism that makes us forget original controversies and remember past experiences with fondness. The label “super predator,” once seen as overblown or forced by the narrative, is now not only accepted but actively embraced. Thanks largely to the nostalgia effect, the Spinosaurus from Jurassic Park III has become the ultimate dino villain.
Then comes Jurassic World Rebirth (2025), where Spinosaurus returns in updated form: a wider sail, paddle-like tail, and semi-aquatic body. And it’s no longer a unique titan, but four (five?) individuals shown almost as sidekicks to Mosasaurus, sharing scraps. SlashFilm accused the film of sacrificing Spinosaurus’s spectacular soul in pursuit of science, forgetting the uproar the character once caused, and overlooking the fact that many of Rebirth’s narrative choices have little to do with science at all. What we’re watching is a complex cycle of rejection and reevaluation, where the public continuously generates new nostalgias, even for things they initially rejected.
Round and round it goes: anyone who dares tamper with this blurry balance — updating, reinventing, taking risks — faces a storm of criticism. Yet even that continuity is an illusion. Dinosaurs have changed from film to film, decade to decade, medium to medium. Jurassic Park itself, in 1993, left behind the imagery inherited from early paleoart and cinema to bring to the screen something more in line with the scientific knowledge of the time.”
If we’d applied the same status quo bias back then, we would have rebelled against them too, demanding stop-motion creatures in the style of Ray Harryhausen. And yet today, we defend them as untouchable, forgetting that Spielberg and his team made bold choices without worrying too much about the consequences.
So what has all this meant for the saga — and beyond? Within the franchise, every sequel has wobbled between innovation and preservation, trapped in a fragile balance: trying to reinvent, while still giving audiences what they recognize. Outside the films, Jurassic Park’s influence has swept through museums, documentaries, games, art, and science communication, cementing a visual model so powerful it makes even the most accurate reconstructions seem “wrong.” Here’s the deepest paradox: in a franchise where no dinosaur is pure, the audience arbitrarily decides what counts as “animal” and what counts as “monster.” And they do it not based on science or story, but on emotional bonds. As long as a dinosaur fits the image we’ve built, it’s acceptable. When it breaks that boundary — too realistic, too mutant, too different — it becomes a monster. But really, the monster has never just been on the screen. It’s been in our heads all along.
Maybe the point isn’t whether dinosaurs on screen should be realistic or monstrous. Maybe we should ask ourselves why we’re so afraid to accept dinosaurs for what they really were: animals. Extraordinary, unique, magnificent animals. And no, science hasn’t ruined dinosaurs. On the contrary, it’s made them even more incredible. Maybe it’s we who stubbornly prefer myth over wonder.
