seven memory sins:

 - of omission:

	1. transcience - normal loss of memory over time, begins within hours, might clear mind to focus on more important information

	2. absentmindedness - wandering away, like losing keys or forgetting where youve put something just a second ago - some scientists say it clears the way for our brains to be more creative, for the brain to work away on ideas

	3. blocking - tip of the tongue feeling, you know that you know something, but just cant get it out

 - of commission:

	4. misattribution - when you remember doing things that you didnt do, or jumble up your memories, eg. you think youve told a friend something, but you actually talked about it with a different friend, or you could swear that the actor that played in this movie is X, but it was actually Y - clearly believing, that youre remembering it correctly

	5. suggestibility - creating outrightly false memories, such as through others' suggestions - comes from outside information - children especially vulnerable - the police manipulating eyewitnesses testimonies

	6. bias - the past is distorted by what we know/feel in the present, five types:
	a. consistency bias - we get more consistent over time, we remeber feeling the same way about something in the past, as we do in the present, even though it was quite different then
	b. change bias - when people think they should have changed something in their lives or about themselves over time and exaggerate the actual amount of change that happened - also how bad it was in the past
	c.  hindsight bias - people believe they always knew something, that theyve in fact just found out about - stronger when after the fact it seems to people that there was a good reason to have the correct view initially
	d. stereotypical bias - contributes to racial/gender stereotyping - preordained, general views about a category of people are projected onto individuals
	e. egocentric bias - memories distorted in a self-flattering way - more credit for success than failures - creative self-deception - comes from putting yourself in center of the action in life, thinking that it all has to do with you somehow

	7. persistence - when you cant forget disappointments, moments of shame, rehearse those hurtful memories - they can haunt us for our whole lives, like memories of rape and abuse - may lead to PTSD - depressive people more likely to ruminate - tends to undermine any sort of critical thinking, even though ruminator are convinced that dwelling on the experience will give them some valuable insight
