Four Things You've Been Told About Your Home That Aren't True

I read the research on homes and behaviour because my clients deserve better than decorating folklore. What I have found, over and over, is that the most quotable findings are often the ones that did not survive being checked.

This is not an argument that environment does not matter. It plainly does, and I have written elsewhere about ceiling height and window views, both of which hold up well.

It is an argument for knowing which is which — particularly when you are about to spend money, during a year when money and energy are already short.

1. "Paint it blue and you'll be more creative"

This comes from a 2009 study by Ravi Mehta and Rui Zhu, published in Science. The finding was elegant: red backgrounds improved performance on detail-oriented tasks, blue backgrounds improved performance on creative ones. It travelled fast, and it is still quoted in design articles today.

In 2014, Kenneth Steele at Appalachian State University attempted to replicate the anagram portion of it. He did not find the effect. His paper is titled, plainly, "Failure to replicate the Mehta and Zhu (2009) color-priming effect on anagram solution times."

Subsequent work has been mixed at best. What that means in practice is not that colour is irrelevant — colour affects mood, perceived temperature, how large a room reads, and whether you like being in it, all of which matter. It means you should not repaint an office blue expecting measurably better ideas, and you should be suspicious of anyone who tells you to.

Choose the colour because you want to live inside it. That is a better reason than a study, and it is one that cannot be retracted.

2. "A messy desk makes you more creative"

The 2013 study behind this one, by Kathleen Vohs and colleagues at the University of Minnesota, is genuinely charming. People seated at a disorderly desk generated more inventive uses for a ping-pong ball than people at a tidy one. Every person who has ever been nagged about their office took it to heart.

In 2018, a team published a replication in Frontiers in Psychology with roughly twice the sample size — a hundred participants after exclusions. They found no effect. Disorder did not improve creativity, and it did not impair executive function either. Their conclusion was that the relationship "seems elusive" and does not support what the popular press had made of it.

I find this one the most practically useful of the four, because clutter in a home during a transition is almost never a creative strategy. It is a backlog. Boxes that have not been opened, a dining table serving as a filing system, a spare room absorbing an entire former life. There is no evidence that leaving it there helps you think, and a great deal of clinical literature suggesting that unresolved household disorder correlates with stress, particularly for women.

You do not have to be tidy. You are allowed to want the table back.

3. "Open plan is better" / "Open plan is worse"

Both of these get stated with total confidence, usually by someone selling you a wall or selling you its removal.

The office research does lean one direction: studies of open-plan workplaces fairly consistently find more distraction, more noise complaints and, in some cases, less face-to-face interaction rather than more. But offices are not houses. The constant in that research is involuntary exposure to other people, which is not what an open-plan kitchen in a family home is doing.

For homes, the honest answer is that it depends almost entirely on who lives there and what stage they are in. A newly single parent who wants to see the children while cooking and a widow who finds a large open floor unbearably echoing are both responding sensibly to the same layout.

This is the one I will not give you a rule for. It is a question about your life, not about architecture, and it is one of the first things I ask about.

4. "Decluttering will make you feel better"

Sometimes. Not always, and not in the way the phrase implies.

The claim in circulation is roughly that removing possessions produces emotional relief. What I see in practice is more complicated. Done too early, or by somebody else, clearing out a house after a loss or a separation can be actively harmful — people describe it afterwards as having been robbed, even when they agreed to it at the time.

What does appear to help is agency. Deciding, yourself, at a pace you set, with the option to defer. The relief seems to come from having made the decision, not from the absence of the object.

Which is why I never arrive at a house with a skip and a schedule. The sequencing matters more than the volume, and it is the subject of a longer piece on deciding what stays.

So what does survive?

Less than the internet suggests, and enough to work with:

• Daylight. Among the most robust findings in the whole field, across mood, sleep and cognitive performance.
• Views of nature. Ulrich's hospital study has been replicated and extended for forty years.
• Spatial volume and enclosure. Ceiling height reliably shifts the kind of attention people bring to a task.
• Noise. Chronic uncontrollable noise has well-documented effects on stress and concentration. This one is not in dispute.
• Control. Being able to adjust your own light, temperature, privacy and layout matters more than any particular setting of them.

Notice that none of those are style decisions. They are structural, and they are mostly free to act on.

Why I bother with any of this

Because people in transition are unusually vulnerable to confident advice. You are exhausted, you are making decisions you have never made before, and a great deal of the industry around you is incentivised to sound certain.

I would rather tell you that the colour study failed to replicate and that I chose the paint because it suits the light in your north-facing room. The second reason is the real one, and it was always the real one.

If you want to go further into the research, Donald M. Rattner's My Creative Space is a thorough and readable survey of the environmental psychology literature on creativity at home, and it is where a number of these threads lead.

Just check the footnotes. That is the whole discipline.
