you can know too much

A yearly review of your portfolio is frequent enough.

Real Hourly wage

Annual Earnings - Annual costs (divided by) Hours spent on Work- Related tasks

Small tweaks can have big results

Assumptions should be positive, rather than the negative. Opt out a participating rather than opt in to participating.

Mental Accounting

Leads you to treat college savings or an emergency fund as sacred. Ideally we should view all money as the same. (Park "found" money in a savings account or investment account until you decide what to do with it.

Bigness Bias...

Tendency to be indifferent about small numbers, although it can cost big bucks

Probability Illiteracy

Tendency to fail to understand the role of odds and chance

Money Illusion

Tendency to ignore inflation

Satisfiers

looking for a good enough solution, make choices through combination of the best available information, gut instinct, and the advice from a trusted screener

Loss aversion

Basic concepts of the inconsistent way people treat losses and gains: (Tendency to take more risk if it means avoiding a sure loss, tendency to be more conservative (less risk) when given the chance to lock in a sure gain)

Trade off contrast

Choices are enhances or hindered by the the trade-offs between options, even options we would not choose anyway.

How to avoid choice conflict

Choose fewer choices Remember: deciding not to decide is a decision Don't forget opportunity cost Put yourself on autopilot Make deadlines work for you Play your own devil's advocate If you are not an expert, ask one

Fungible

Every financial decision should result from a rational calculation of its effect on ourother all wealth. Intellectually difficult and emotionally taxing, to calculate the cost of every short-term transaction (to deal with this daunting task we create mental accounts) ($100 won at roulette table, $100 earned, $100 from grandma)

Hindsight Bias

People conveniently remember their successes but repress or forget their failures.

Confirmation Bias

It's hard to prove yourself wrong. Enlist the help of a "trusted scanner". Tendency to search for, treat kindly, and be overly impressed by information that confirms your initial impressions or preferences. Once you develop a feeling about a subject - no matter how unconscious that preference might be- it becomes hard to overcome your bias- first impressions are very important.

Prospect Theory

Losses hurt you more than gains please you. Saving money through payroll deduction is experienced as a foregoing gain (passing up the bigger check) rather than an outright loss (paying into savings "out of pocket").

Decision Paralysis

Makes the idea of many proactive decisions daunting and uncomfortable

Three regular issues with humans and numbers

Money illusion, probability illiteracy, bigness bias

Sunk Cost Fallacy

Money that's spent is money that doesn't matter. (The past is the past, what is important is what is likely to happen next) (What if you keep going to the gym and working out because the membership cost you so much and you paid for a year long membership) Its all in how you look at it. (Rejection vs. selection or protecting gains vs. avoiding losses. Go with the positive "selection" and "gains".

Extremeness Aversion

People are more likely yo choose an option if it is an intermediate choice within a group, rather than at one extreme end.

Status Quo Bias

People are naturally disposed to favor the familiar and keep things much as they have been.

The ego trap

People tend to invest something that they are familiar with. But something familiar (e.g. toothbrush you use, donuts you buy, car you owned) does not always mean that it is a sound investment. People confuse familiarity with knowledge.

Endowment Effect

People tend to overvalue what belongs to them relative to the value they would place on the same possession or circumstance if it belonged to someone else.

Regret aversion

People want to avoid the pain of regret and the responsibility for negative outcomes

reflexive system

Reaction as soon as something happens (when something good/bad happens) (when you get a new car and go show it off)

Conformity

Result from uncertainty, we follow others because we don't know what to do, allowing the judgment of others to steer you into unwise investments, or out of sound ones. We often feel that by doing what everyone else does is not a bad thing.

Head I win, Tail It's Chance

The idea is that when things happen that confirm the correctness of your actions, you attribute the events to your own high ability, Conversely, when things happen that prove your actions to have been mistaken, you attribute those discomforting events to some other cause which you had no control.

Sacred Money

The tendency to mentally account for money as so sacred we become to conservative with it.

Mental Accounting (cont.)

The tendency to value some dollars less than others and thus waste them. The inclination to categorize and handle money differently depending on.....(where it comes from, where it is kept, and how to spend it) (storage, purpose, source)

Herding

The trend isn't always your friend. (Know they self!)

Prospect theory

The way we frame decisions, the ways we label outcomes.and how they affect our attitude toward taking risks. An attempt to incorporate psychological principles (such as Weber's Law) to explain why people choose the way they do

Marginal Propensity to Consume

To spend more because you just got some extra money. You get a tax refund and it makes you spend more because you feel that you have extra money.

Decision Paralysis

Too much choice makes choosing tough. Enlist the help of a "trusted scanner" to pare down chooses. (Use Consumer Reports)

Maximizers

Want to know everything about a choice; spend a lot of time, effort, and emotion researching options, hope to make the best choice possible
