Why we are choosing liars as leaders ?

 First if the country is big and information space is cluttered by partisan propaganda and you don't have reliable source of information you can't decide 

If Trump says that Haitians are eating pets in Ohio, if you are in Texas you can't verify.

If the country is small then you might meet someone from Ohio to tell you that is truth or not.

Second is the bias, I admired Elon Musk and I discarded bad info about him until I watched a documentary on how he took over Tesla and kicked out the founder.

I also admired Jordan Peterson and I also rejected the criticism from the left till he expressed his opinions on war on Ukraine.

I admired Obama till I found out about his decisions regarding Afghanistan and 2008 bailout.

So to get rid of political bias you have to exposed to the truth, which is is hard in big connected world 

Or you should be exposed to well explained information for a long time, which is hard nowadays, when TikTok are few seconds long.

We should get rid of the notion that rational people will take rational decisions and choose the best people. 

We should go to a more Darwinian solution:

These should be a selection from a largely pool for candidates and a selection out for the leaders.

USA has a low selection pool, only 2 parties, and this causes the degerecy of the political class 

Russia and similar dictatorships have also the problem of selecting out of he dictator.

Despite blunders in Ukraine Putin is not overthrown.

Biden despite his mental state is ruling the country. 

In Roman Empire, legions made emperors and also legions overthrew them.

In middle ages feudal lord were deposed by rivals.

This stock refreshed the leadership and allowed survival of the state entity despite a crude and inefficient selection system for leaders.

My idea is: if we can't choose the best leader anyway, let's make possible to depose him peacefully I'd he is not fit 

In conclusion USA democracy has 2 problems: Low Pool of candidates and  low probability to change the president if it is ill (Kennedy,Reagan,Biden), incompetent (Trump), corrupt (Lyndon Johnson).
