Anyone who has reached an opinion about independence, for or against, has dealt with one argument above all others.
There will be those on both sides of the land reform debate who will have been disappointed by the interim report of the Land Reform Review Group, published this week.
It argues decisions by UK governments – from the failure to invest in an oil fund in the 1970s and 1980s to cuts to capital spending in the past few years – have undermined growth.
In fairness, the Scottish Government's paper on the economic case for independence is not intended as a policy document.
UK economic decisions have been holding Scotland back "for generations," Nicola Sturgeon has claimed, as the Scottish Government prepared to publish a key report on the country's industrial strengths.
