Rats are neophobic, which means they fear new things. However, they only have a three day or so memory. So when you set out a poison bait station, they avoid it for the first few days.
The "illusion" they have after that, is that they think the box has always been there then. Because they can no longer remember a time when it wasn't. So they go in and eat the poison bait, because they no longer fear it as "new".
The rats in "Mrs. Frisby and the Rats of NIMH" have the illusion that they need to rely on humans for survival. Through their experiences and learning from their time at NIMH, they gradually realize their own intelligence and capabilities, leading them to break free from this illusion and create their own independent society in Thorn Valley.

Rats are neophobic. Which means they fear new things in their environment. But they have a very short memory, only about three days. Therefore, if you put out a poison bait trap for them, they'll avoid it for a few days. But the illusion they suffer is this - after that few days, they "believe" that the box has always been there! For they can't remember a time in their life when it wasn't. So they go in and eat.
