How often have you suggested, “Oh, let’s try something new; let’s do some fancy thing!”? Did you know that this could potentially contradict Jakob's Law?

The user Mental Model works based on beliefs, not facts. Mental Model is what the user believes about the system, and it helps the user predict how the system will work.
Users often create mental models by using the knowledge they have about the world to create them.
It's worth noting that Mental models can change over time — due to additional experience with your system or with other systems.
