Design, behavior and social interaction study

A phenomenon relationship I notice happens between, Noodlehead, a popular thai fusion restaurant, and Millie’s Homemade Ice Cream, an ice cream store locates right beside Noodlehead in Pittsburgh East Liberty neighnorhood. Often, customers finish meal in Noodlehead and go straight to Millie’s Homemade Ice Cream store for icecream.


In Noodlehead and Millie’s Homemade Ice Cream

One day during finals week, some friends and I arrived Noodlehead for dinner.

Mental stage:

  • stress
  • need a break
  • hungry

Original plan:

Dinner at Noodlehead -> Millie’s Homemade Ice Cream

Why go both?

  • balance of salty & sweet flavor
  • routine
  • close by

What happened:

Millie’s Homemade Ice Cream -> Noodlehead

Why switch the order?

  • Feeling need to spend finals precious time on something, not standing and doing nothing
  • friend’s suggestion
  • save time. The plan was to get Millie’s after Noodlehead anyways
  • probably same satisfaction to go before or after. The order does not matter.

We decided to get Millie’s ice cream while waitng to be seated. After finishing the ice cream, we felt not as satisfied and comfortable as when we imagined eating them. I wonder why did we made the decision to eat the ice cream before dinner, even though we knew we will feel terrible after eating them?

The process of decision making to visit Millie’s before Noodlehead:



I am interested in looking at the situation when one desire for a thing, and knew the thing was not beneficial, but one still get it.

How does one sell the one’s desire to oneself?

How does one make decisions?


willpower or self-control is low;

tired mind decrease decision quality

or simplify decisions by accepting our immediate desires.

implicated in

prosocial behavior

— Empathy plays a strong motive

ex) helping, sharing donating, co-operating, and volunteering.

Ego depletion hinder the ability ot engage in reflection, meaning harder for one to feel guilty, which inderctly effect one to give or benefit otheres.


“identifying a decision, gathering information, and assessing alternative resolutions.”

“find” or “discover”.

any apporach to problem solving, learning, discoverying for

immediate goals.

As decision makers,

  • no infinite resources or time to gather and analyse information.
  • limitations to the amount of complexity to cope with
  • make decisions based on rational process
  • simplify assumptions and accept limited availabliity of information
  • we use Heuristics technique as a way of reducing the complexity of decision making”

ex) associating a particular brand with quality, rather than engage in detailed evlautaion.

some approaches:

  • framing the problem
  • using information
  • problems of judgement
  • post-decision evaluation

When making decisions:

  • Situate at specific time and space, I need to make a decision.
  • Throw out a question first.
  • Thinking about time and space constrains, then checking how I am feeling.
  • Imagine scenarios.
  • Filtering options environments and people around me.
  • I often physically situate myself at a space first, which filtered many choices already, then make decisions based on how I feel and how others are feeling.
  • My decision making process shuts down, when external factors comes up.
