“We did not find that meditation had any negative effects, however the good impacts can be compared to a placebo effect.
“A person may have the expectation of becoming a better person through meditating, and may believe that to be the case – but in fact this has not been proven.”
Initial analysis carried out indicated that positive effects were seen by making people feel moderately more compassionate or empathetic, compared to if they had done no other new emotionally-engaging activity.
However further analysis revealed it played no significant role in reducing aggression or prejudice or improving how socially-connected someone was.
