Funny how you don't often hear this kind of argument made for estimating the prevalence of tax fraud. And there the risk vs reward calculation is much worse. I would trust more common sense arguments. People who respond to economic incentives are economically motivated.
You're getting this backwards. Claiming most asylum refusals are due to fraud without anyevidence is the opposite of common sense
Also having an economic as well as other reaspns to immigrate does not mean someone isnt a qualified refuge or or not facing persecution or are committing fraud.
Taxes are complicated just like our immigration system. Many people make innocent mistakes every year, most people don't want IRS to come down as hard as they can on every innocent mistake by treating it as fraud without any proof. They expect corrections and if necessary small fines.aw
"Any evidence" is a low bar. Obviously there's evidence of many kinds. The point here regarding common sense is the evidence of human nature when it comes to lopsided risks versus rewards, and widespread knowledge of this imbalance. Legally proving fraud is obviously difficult in a world where there is almost no paperwork to go on (save what the applicant chooses to provide), and hardly worth the effort when the government can just stop investigating when it looks doubtful and reject the application for the same practical result. In the US most applicants are rejected and aside from obviously-suspicious ones who skip their hearing, the most common reason is literally that their fear isn't found to be credible. Also, a person who has multiple motivations but only lists the ones that would benefit them has lied by omission.
