This should be taken with a huge grain of salt: The article pointed is dated Feb 2015 but see all these articles: [1] from September 2014 [2] from Feb 2015 [3] from September 2014 [6] : From August _2012_ All from this "Dr. Travis ..." . They all quote "New research from Johns Hopkins Medical School" , without ever giving the source of that research. If you google a bit for it you will find some information from Johns Hopkins University[4] : "Caffeine Has Positive Effect on Memory"; some study [5] from The Johns Hopkins Precursors Study in 2002 (so hardly "new") discuss about coffee, but "these associations were not statistically significant". You will notice that from August 2012 to February 2015, it was always "New research" In conclusion, this LinkedIn blog post (from which all articles copy/paste from) lacks a lot of sources, especially if written by someone who holds a dual Ph.D. in clinical and industrial-organizational psychology (according to his Forbes personal page).
