I build intelligent systems for human complexity.
I'm Jonathan Doriscar — a cognitive scientist, computational behavioral scientist, and founder working across memory, language, behavior, data, and AI.
I design experiments, model behavioral data, and analyze language at scale to study how people make sense of complicated information.
Currently finishing my dissertation and building MemwaMind.

Methods and tools
Methods I use across research and product work.
I use the same core toolkit across projects: experiments and statistical modeling, large-scale language analysis, machine-learning evaluation, and reproducible workflows.

Research computing and data science profile
My Northwestern profile covers applied data science work in R, Python, natural language processing, machine learning, and research computing.
Social Cognition
Unsupervised machine learning in social cognition
My Social Cognition article uses K-means, DBSCAN, PCA, and market basket analysis as discovery tools.

Why Reform Stalls
A two-study working paper combining 257,401 YouTube comments with a behavioral experiment.
Inside the work
How I make complex questions testable.
Each project called for a different method: clustering, large-scale text analysis, an experiment, coding institutional records, or designing an accounting review workflow. Explore the choices behind each analysis and how I interpreted the results.
K-means clustering, K = 5
Cluster centers from Project Implicit data on Black-White Implicit Association Test (IAT) responses, N = 13,855.
Strongly liberal, with measurable pro-White / anti-Black implicit bias paired with warm explicit feelings: a gap between the explicit and implicit measures.
Data and code: From Data to Discovery (Doriscar et al., 2025, Social Cognition). This view uses the paper's Project Implicit clustering example and reported cluster centers.
From social attitudes to interpretable structure
Inputs: large-scale attitude data, Project Implicit Race IAT worked examples, responses and items that may contain hidden structure. Output: possible clusters, dimensions, and co-occurring response patterns that researchers can interpret with theory.
- Topic
- Social attitudes and belief patterns
- Method
- Unsupervised machine learning
- Paper or project
- From Data to Discovery - Published in Social Cognition
- Why it matters
- Clustering can surface patterns in attitude data; theory is what gives those patterns meaning.
- Scope
- This view uses the paper's Project Implicit clustering example and reported cluster centers.
Selected projects
Three projects in depth.
Open a project for the question, study design, methods, and findings.
Unsupervised Machine Learning for Social Cognition
Using unsupervised machine learning to explore patterns in beliefs and attitudes.
Role: Lead author.
Why Reform Stalls
Modeling public justification, outrage, and reform discourse around police violence.
Role: I conceived and led the project, including study design, data curation, analysis, validation, visualization, and writing.
Historical Blame and Collective Responsibility
Understanding why people hold present-day groups responsible for past harms.
Role: Coauthor.
Founder project
I’m building MemwaMind.
The accounting agent for client work.
Finding the document behind a prior conclusion.
Carry approved client context into the next period.
