1. You See Everything - 11 Trillion bits bombard your system every second. How many do you consciously recognize? 50. That's it. Which means all that you see, hear, taste, smell, and feel is just the beginning of what's out there. You are consciously aware of a staggeringly little amount.
2. You do See Everything....sort of - The remainder of those 11 Trillion bits outside of your conscious awareness don't go to waste. You respond to them through other ways. Ever notice your jaw clenched without realizing you were upset?
3. It Fills in the Gaps - How many of each animal did Moses put on the Ark? 2 right? Nope. Read the question again. Look at the name. If you missed it don't worry. So did I. The brain takes familiar information and fills in gaps. For example, it sees "animal" with "ark" and assumes you're talking about Noah.
4. Just Read This - I cnduo't bvleiee taht I culod aulaclty uesdtannrd waht I was rdnaieg. Unisg the icndeblire pweor of the hmuan mnid, aocdcrnig to rseecrah at Cmabrigde Uinervtisy, it dseno't mttaer in waht oderr the lterets in a wrod are, the olny irpoamtnt tihng is taht the frsit and lsat ltteer be in the rhgit pclae. The rset can be a taotl mses and you can sitll raed it whoutit a pboerlm. Tihs is bucseae the huamn mnid deos not raed ervey ltteer by istlef, but the wrod as a wlohe. Aaznmig, huh? Yaeh and I awlyas tghhuot slelinpg was ipmorantt! See if yuor fdreins can raed tihs too.
5. You Think You Know - Ever knew something that you KNEW you KNEW only to realize you were wrong later on? Like mixing information together in #3, we group data in our brains in certain ways. Sometimes the "wires get crossed" and what we thought was right was a incorrect grouping of similar information.
6. Finds Middle Ground - Go the store and look at coffee. Of all the brands, you're most likely to choose the one priced in the middle. Not the highest (you're not a Rockafeller). Not the lowest (you do want some quality). You almost always pick right in the middle. Study after Study prove it.
Can you trust your brain? Yes, to a degree. Just remember that for everything you see - there's more to discover.
