The model of appropriation presented here represents a simple model of reasoning that brings together concepts from rational choice theory and cognitive science to shed light on human cognition and behavior related to the human capacity of identifying better technology. The framework positions the user in the state where he has already decided to try some product after evaluation. Using generic simplifications from related literature in the fields mentioned above, the author describes the model of appropriation both verbally (linking concepts) and formally (using equations). The major contribution of the paper is its identification of characteristics that help differentiate between final rejection and adoption of the product being evaluated.

The paper references important previous results in rational social choice cognitive science, such as the fact that rational choice approaches are used for simple evaluation tasks, whereas so-called irrationality models are used for more complex tasks. One major outcome of the paper is its presentation of the distinctive operations of a human mind that is in the process of analyzing better technology. Concepts such as anchors, gradual adaptation, linear models, and chains of reasoning are imperative to build a model of reasoning in which the user evaluates positive factors (benefits, utility, pleasure, and surprise) and negative factors (cost, pain, and disappointment). The simple appropriation scenario begins with a person deciding to try a product. The model of appropriation includes the willingness to try, mastering, level of stability, enthusiasm, expectations, boredom, patience, and continuation. Furthermore, to better understand the importance of each component, the author develops a semi-formal numeric representation focused on evaluation of the enthusiasm dimension at each step of the appropriation mode, through formulas.

The main result here shows that higher enthusiasm does not necessarily mean a higher success rate or higher acceptance. Even though the model is based on general concepts, possible extensions can consider partial appropriation, such as technology products that are partially or temporarily rejected or accepted.
