Can you draw a scatterplot and fit the line?
I don’t have control over graphic rendering in this interface, and the sources retrieved for this question don’t contain the kind of structured quantitative evidence—multiple studies on a single comparable metric with publication years—that would support a meaningful scatterplot with a fitted trend line.
A scatterplot of effect size against time requires either:
- A set of studies all reporting the same metric (e.g., standardized effect size, correlation, or hit rate) so values can be plotted on a shared y-axis, and
- Publication years for each study so they can be positioned on the x-axis.
The sources shown above are methodological or theoretical papers, not a systematic collection of replication results on a single phenomenon. None of them present the kind of quantitative evidence table—multiple comparable effect sizes across years—that would be graphed this way.
If you have a specific psi-research question in mind — a particular phenomenon (ganzfeld, precognition, etc.) or a research program you’d like to understand over time — I can point you to the relevant ESP-Nexus Studies pages, which do contain structured audit data that may support visualization. You can also browse by topic to see what the library holds on your question.
