The problem with this is that there is zero evidence that the filtering and testing requirements correlate with actual doctoring skills. In fact there is evidence against this.
Think of it this way; in Europe it is far easier to become a doctor then in the US due to significantly less stringent requirements. However in Europe and other 1st world countries treatment and other quantitative measures on quality of medical care beat the US by a far margin.
It shows that the "unpleasantness" is pushing something to the right of the bell curve. However it is clearly not pushing "effective medical diagnosis and treatment" to the right of the curve as Europe is beating us on that front with far less stringent requirements.
