Listening music only through left ear as a way to increase focal processing

i am recently trading crypto. I am trying to understand the concept of risk. I just found this in wikipedia

"Framing involves other information that affects the outcome of a risky decision. The right prefrontal cortex has been shown to take a more global perspective[65] while greater left prefrontal activity relates to local or focal processing.[66]

From the Theory of Leaky Modules[67] McElroy and Seta proposed that they could predictably alter the framing effect by the selective manipulation of regional prefrontal activity with finger tapping or monaural listening.[68] The result was as expected. Rightward tapping or listening had the effect of narrowing attention such that the frame was ignored. This is a practical way of manipulating regional cortical activation to affect risky decisions, especially because directed tapping or listening is easily done."

I am trying it by myself.It works. Listening music thru left ear do make me focused. Worth a try
