The Tapping Evidence Base
The Tapping Evidence Base

The most complete record of the research on tapping anywhere.

An openly-sourced, fully-referenced directory of the published research on Emotional Freedom Techniques (EFT, or "tapping") — every study, every language, in plain English, including the null results and criticisms. Written so anyone can read it, and structured so researchers can build on it.

That's 342 primary studies (trials, outcome studies, case reports and dissertations) plus 125 reviews and meta-analyses — 467 in all.

What this is — and why it's different

Most "EFT research" pages are one researcher's own papers, or a plain list you can't search. This is built to be three things at once: complete (including studies published in Chinese, Korean, Turkish, Persian, Indonesian and more that English-only lists miss), honest (null results and criticisms are in the main list, not hidden), and readable (every study has a plain-English summary before the technical detail).

A note on honesty. When we found effect sizes that looked too good to be true, we checked them against the original papers — and corrected several that turned out to be measurement artifacts. That's the standard here: the goal is a resource a skeptic can trust, not a highlight reel.

The collection spans 263 studies and clinical trials, 125 reviews and meta-analyses, 58 case reports, and 21 dissertations — each labelled by type, so you can weigh a 200-person randomized trial differently from a single-patient report. It also includes 33 studies of Thought Field Therapy, the tapping method EFT grew out of, marked as a related method.
