text: **3.6.4. Lack of education to data**
  
  Boris Müller, professor for interface and interaction design at the University of Applied Sciences in 
  
  Potsda, said in an April 2011 interview:*"I think that really a citizen needs to know how*
  
  *visualizations work in order to really evaluate the quality of the data and the quality of the*
  
  *evaluation."*As data visualization and analysis becomes more popular easier to use (even as a tool 
  
  for manipulating the public opinion), it's important for the public to: 
  
  • understand that, before becoming digital, information was coded, stored and used in many 
  
  ways, through social norms and human interactions more complex than computer ones (cfr 
  
  the digitization of India land ownership records), therefore making exact, one-to-one 
  
  equivalence between analog and digital procedures hard or impossible in many cases 
  
  •  think critically about where data comes from 
  
  •  *remember*to always follow the*development*of data-based stories, or accusation.
