A hypothesis is a liability
A Research Paper by Itai Yanai & Martin LercherThere is a hidden cost to having a hypothesis. It arises from the relationship between night science and day science, the two very distinct modes of activity in which scientific ideas are generated and tested, respectively [1, 2]. With a hypothesis in hand, the impressive strengths of day science are unleashed, guiding us in designing tests, estimating parameters, and throwing out the hypothesis if it fails the tests. But when we analyze the results of an experiment, our mental focus on a specific hypothesis can prevent us from exploring other aspects of the data, effectively blinding us to new ideas.

A Short Story by Samuel H. Scudder & Buster BensonA Need to Walk
An Essay by Craig ModWalking intrigues the deskbound. We romanticize it, but do we do it justice? Do we walk properly? Can one walk improperly and, if so, what happens when the walk is corrected?
You and Your Research
A Speech by Richard HammingThis talk centered on Hamming's observations and research on the question "Why do so few scientists make significant contributions and so many are forgotten in the long run?"
The Spoken and the Unspoken
What is unspoken
Ethnographic studies are distinct from ethological research in other species because we can speak with our subjects and ask them questions. This has tremendous value, but much of what humans do is not spoken, and we also observe, count, and measure.
Research questions
From my records, research questions emerged that I never expected when I was making them.
Quantitative data collection
Quantitative data collection involves systematic and repetitive observations on the same set of variables.
Anthropological rapport
Accurately capturing how people spend their time is contingent not only on systematic data collection, but also on participants moving in a relaxed and normal manner through their daily activities. Just as primatologists habituate their subjects to their presence, anthropologists first must develop rapport and trust with the communities in which they live.
Scan samples, focal follows
Scan samples and focal follows are two commonly used behavioral observation methods.
During a scan sample, randomly selected individuals are located at specified time intervals, usually every ten to fifteen minutes, and the observer instantaneously records what the participant is doing.
Focal follows complement scan samples by documenting the continuous sequence of an individual's activities. During a focal follow, each subject is observed over a period of several hours with each change in activity recorded with a start and stop time.
Multitasking
In most traditional societies children help care for their younger siblings. However, it is often the case that a child minding his younger sibling does so out of the corner of his eye while playing with other children. Is this play or child care?
A nested classificatory hierarchy
I organized behavioral codes to contain several levels of information. As in this example, if a child is outside playing with friends while minding her two-year-old sister, the activity was coded as 675: the 600 signifies noneconomic activity, the 70 that it is playing, and the 5 that it is playing while in charge of a child. All activities were coded in this way. A nested classificatory hierarchy preserves both detail for future research and flexibility to lump or disaggregate activities for analyses. This method of nesting information carries over into many kinds of coding and classificatory schemes.
A child's question
Because they live so successfully in their world, we expect our subjects to readily explain the strategies that underlie the behaviors we observe. This can be trying, because from their point of view we are asking the obvious, a child’s question.
The research agenda
Important connections are often made by accident, outside the bounds of our research agenda.
