Endowed Progress Effect: A phenomenon where people are more likely to complete a task if they are given a head start. This effect used by leveraging known data points to pre-populate areas of the assessment and provide a head start for the user to take across the finish line.

Hick’s Law: The time it takes for a person to make a decision as a result of the possible choices he or she has: increasing the number of choices will increase the decision time logarithmically. This law was used to carefully design the progressive disclosure of data points that have a lesser impact on the assessment value.

Curiosity Gap: The gap between what we know and what we want to know. When a story teases something interesting but leaves a gap in the reader's knowledge, the reader feels compelled to fill in the gap with knowledge. Examples of this gap in practice include property imagery thumbnails at the dashboard level; the use of count badges across the experience; Confidence intervals, and more.

Commitment Bias: The desire to be consistent with what we have already done or decided. This bias was used in the favor of all parties by means of a completeness indicator, which encouraged users to pursue 100% completion.

Framing Effect: Drawing different conclusions from the same information, depending on how that information is presented. By leveraging a custom data model which surfaces contradictory data points so the user, and serving them as alerts, the design frames outliers as something to be investigated.

Paradox of Choice: The observation that more choices can lead to less satisfaction; having too many options can result in anxiety and choice paralysis. An example of this is the interior and exterior cards, which surface just 3 categories each. There are 11 and 16 categories in total, respectively. By limiting to 3 categories before expansion, the design encourages interaction with the more important datapoints, leading to a more accurate assessment value - a cornerstone of this product's value.

Pseudo-Set Framing: The technique of presenting items or choices in a way that suggests a set or collection, motivating individuals to complete the set. This is most easily seen within the Interior, Exterior, and other card-like structures within the design, and encourages completion of each respective card.

Spark effect: people are more likely to take action when the effort is small. By pre-filling as much of data as possible using known or predictive analytics, the remaining effort becomes smaller and easier to digest for the user, increasing completion and thus accuracy.

Perceptual Load Theory: Considering the cognitive demands placed on users' attention and perception and designing interfaces that minimize distractions and cognitive overload. Perhaps the best example of this is the Dashboard, which has deliberate and considerable empty space to the right of the header. Minimizing cognitive overload and complexity.

Mere-Exposure Effect: A psychological phenomenon by which people tend to develop a preference for things merely because they are familiar with them. By starting with the golden spiral and research-backed F-patterns, the application's architecture is instantly familiar to new and existing users, decreasing onboarding time and increasing user satisfaction from the very beginning.
