Schemata are interrelated and multiple conflicting schemata can be applied to the same information. Schemata are generally thought to have a level of activation, which can spread among related schemata. Which schema is selected can depend on factors such as current activation, accessibility, and priming.
Hornets will look for a sheltered location to make their nest, and such nests can be found under leaves, in tree branches, on windows, in attics, under rafters, inside abandoned buildings or vehicles, etc. Any space that is protected from the weather and undisturbed can attract hornets to nest.
Kathy-Langley, BC sent me these photos of a bumble bees nesting in a bird house last spring. This is not an uncommon occurrance. Bumble bees will nest in the ground, in a wall, in a bird house or other structure that will keep the weather out. Bumble bees nest within insulation, grass or other similar materials.
