this is the Guardian's article that I read

Economics may be dismal,

but is it a science?

The problem with the dominant paradigm within economics is not that it
uses modelling or that it rarely uses qualitative methodologies. (Increasingly,
non-exact sciences, including cognitive psychology and meteorology, use
modelling.) Instead, it is that economists’ models are based on assumptions
that are not psychologically realistic and that those assumptions are accepted
without being rigorously tested using both quantitative and qualitative
methodologies. Researchers in behavioural economics and behavioural finance are
working to rectify this situation. However, some of their conclusions remain
tentative and economists have not yet been able to incorporate them into the
sorts of models needed for producing the forecasts that the modern world
requires.

economics should become social sciences. However, the argument is based
on relationship between exact sciences and social sciences. Are meteorology,
volcanology, neuroscience and cognitive psychology exact sciences.

The main ideas raised by this article are:

1. Economists’ models are based on assumptions that are not
   psychologically realistic and that those assumptions are accepted without being
   rigorously tested using both quantitative and qualitative methodologies
2. 
   
   Some of the economics conclusions and behaviours remain provisional
3. 
   
   Economists have not yet been able to incorporate their
   conclusions  into the sorts of models
   needed for producing the forecasts that the modern world requires

For these purposes economics should become social
sciences. However, the argument is based on relationship between exact sciences
and social sciences.
