IMO efficient market hypothesis is not true (assuming you have all available information you could beat it), but for an ordinary person there are so many ways the market is stacked against them that they should still just assume that it is true. The question isn't "is it possible to outperform the market by thinking?", it is "will whatever advantage I can get by thinking weigh up for all the disadvantages I have from not being able to insider trade, being further from the exchange than other market participants, having lower ability to sustain losses than big market players, trading fees, taxes, opportunity cost, etc.?" For any single individual, the answer to the second question is almost certainly no (unless you happen to sit in congress).
