It is not broadened. It is adequately enveloped by the 95% confidence interval curves. 2. It is asymmetric (publication bias). The statistical average of all data (dash-dotted vertical line) does not coincide with the most representative control effect size (dashed vertical line). 3. The data scatter too close towards the peak at 50%. Foundations of Quantum Theory and Consciousness
