The researchers used noticed changes in the data from 2005 to 2016 to project master plan for self-reported life interpretation in 2050. The study report shows that future changes in material variables, as the OECD (Organisation for Economic Co-operation and Development) projects, are likely to yield prudent betterment in global average life evaluations—a rise of zero to 10 percent above current levels.

By comparison, scenarios based on metaphysical variables show a broad range of possible results, from a 30 percent increase in future global average life evaluations in the most positive scenario to a 35 percent drop in the most negative scenario of social decline. Co-author Eric Galbraith, of the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (UAB) in Spain, says.“Possible changes in GDP are very unlikely to play a vital role in changes in life self-evaluations within 30 years,” 

The researchers concluded by saying that “Our results show that the greatest benefits to be potentially made over the next decades, as well as the most dangerous pitfalls to be avoided, lie in the domain of social fabric,”
