&#x2F;&#x2F; she created an experiment on the efficacy of prayer by dividing her exams in two groups, praying for success only on one, the other one being a control group. She achieved the higher marks in the latter group<p>In at least Judaism - and I would expect in other religions, prayer is necessarily partnered with intention[1] - ie what is in your heart matters, not just the words you&#x27;re repeating. Presumably someone creating such an experiment does not engage in the prayer with sincere faith and thus can conclude nothing from the outcome.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kavanah" rel="nofollow noreferrer">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Kavanah</a>
