Hidden Brain - Making the world sparkle again.

Habituation and the hedonic treadmill


Look again - the power of noticing what was always there.

Dishabituation - a break from your routine makes you see your routine anew. Julie Roberts "resparkles" time with her family by returning after shooting a movie. 

Changing your environment primes your brain for taking in information differently and sparking creativity. But the effect only lasts 6 minutes. 


Experiences retain their intrigue far longer than material items. Experiences are recollected over and over, and you habituate slower. 


Giving is much more satisfying than receiving. The rate of habituation of feeling happy is much faster for things you get for yourself. 


Variety enhances psychological experiences. Variety prevents habituation. Variety by definition means there's change, so you can't habituate to it. 


Shorter vacations may be better - vacations peak in happiness at 43 hours. A few short vacations will be more exciting than longer ones. 


People who are asked say they prefer hearing a favorite song without interruption. But when tested, they enjoyed it now if it was interrupted. Same with massage. 


Conversely, distasteful experiences are best done without breaks, so you don't have to re-enter the habituation to the bad. 


People who have had depression returned to neutral emotion slower after bad news. 


Disastrous accidents often happen near the very end of an undertaking. The workers habituate to the danger and take less precautions at the end of the project.

Who was Kilroy?

Interesting history. 
Just Who Was Kilroy?
It is not clear just where the viral "Kilroy Was Here" tradition got started. Soon after WWII ended, the American Transit Association ran a contest to track down its origins. Scores stepped forward, to claim that they had been the originators. Ever since, there has been plenty of research on Kilroy. The likeliest theory traces the meme to James J. Kilroy, a Fore River Shipyard in Braintree, Massachusetts, inspector. That Kilroy supervised the work of riveters who were paid by the number of rivets installed. After they noted that number down, inspectors put chalk marks on the work done. However, some unscrupulous riveters erased the mark, in order to get paid twice for the same work. To avoid that, Kilroy wrote "Kilroy was here" in harder-to-erase crayon.

Kilroy's crayon marks would normally have been painted over. Wartime was hectic, however, and in WWII, that didn't always happen. Thousands of GIs came across "Kilroy was here" on ships built at Fore River Shipyard. None of them knew who Kilroy was, but they wondered, and that minor mystery birthed a viral meme tradition. The hardest to reach ship locations were the likeliest to go unpainted. The presence of the crayoned phrase in those spots enhanced Kilroy's reputation for getting into impossible-to-reach places. When they got off their ships, many servicemen continued the gag about the mysterious Kilroy. They ran with it, and tagged every available surface to let the world know that Kilroy had been there. Somebody at some point added an easy-to-imitate drawing of a big-nosed cartoon character to the gag. The phrase and drawing combination took Kilroy from a widespread meme to major viral history.

Reserve rides ahead of time at Disney world

Just in time before we have grandchildren, Disney is introducing reservations a week ahead for theme park rides, if you're staying at one of their hotels. 
"guests will be able to reserve rides and shows ahead of time...Guests staying at Disney World's resort hotels can make selections up to seven days in advance, all at once, for up to 14 days of their stay." 

Submarine diving and surfacing mechanics




8:51 A submarine's buoyancy is affected by the temperature and salinity of the water. Melting arctic ice gives areas of low salinity that have to be measured and accounted for. 

During surfacing, orientation in 3 dimensions is very critical, so that (23:20) "just the weight of one person walking from forward to aft of the ship will upset the balance," so an order is given to not walk around, just as they're surfacing. 

21:55 If the submarine has any momentum from a sideways current when surfacing through ice, and if the vertical "punch" through the ice isn't forceful enough, the submarine could violently roll rather than punch through, damaging tail planes and prop.
