Psychological Value Theory: Predicting Initial Romantic Partner Choice From a General-Purpose, Computational Cognitive Model of Value-Based Choice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Mate value is theorized to be a key driver of romantic partner choice, yet the cognitive mechanism underlying romantic partner choice remains poorly understood. Here, we assess whether initial romantic partner choice can be predicted by a general-purpose, computational cognitive model of value and choice. To do so, we enlist Psychological Value Theory (PVT), which predicts both choice and decision reaction time (RT) simultaneously. To establish the scientific controls necessary to test PVT's strong a priori predictions, we use discrete choice experiments. Experiment 1 tested choices between partners described by single features, while Experiment 2 investigated how the values of multiple features are integrated. PVT's predictions were highly accurate across both experiments, accounting for over 85% of the variance in choice and RT for groups and individuals. Critically, Experiment 2 revealed that people integrate multiple features via a Biased Average algorithm, where the most positive feature holds disproportionate influence. These findings indicate that initial romantic partner choice recruits a general-purpose, value-based decision mechanism, providing a computational framework that can be extended to model partner choice in more complex, real-world contexts.
