Question 1

What does research say makes a face attractive?

Accepted Answer

Three properties recur consistently across studies, though the picture is more complicated than the popular summaries suggest.

**Averageness.** Composite faces — produced by digitally averaging many individual faces — are reliably rated **more attractive** than most of the individual faces used to make them. This is counterintuitive but well replicated since Francis Galton's nineteenth-century photographic composites. One explanation is **processing fluency**: average faces are easier for the visual system to process, and ease of processing is experienced as pleasantness. Another is that averageness signals genetic diversity or developmental stability.

**Symmetry.** Faces closer to bilateral symmetry tend to be rated higher. The proposed reason is that developmental disturbance — illness, malnutrition, genetic load — produces asymmetry, so symmetry signals developmental stability. The effect is real but **smaller than commonly claimed**, and some studies find it weak once averageness is controlled for. Nobody is actually symmetrical, and manipulated perfectly symmetrical faces often look unsettling.

**Sexual dimorphism** — features typical of one sex. Findings here are the least consistent. Preferences for masculine male features vary by context, culture, and the rater's own circumstances, and several widely reported effects have replicated poorly.

**What complicates all of it:**

**Familiarity matters substantially.** The **mere exposure effect** means repeated exposure increases liking, so people you see often become more attractive to you.

**Culture and era shift standards** considerably, particularly for features other than the three above.

**Non-facial factors dominate in practice.** Expression, eye contact, perceived warmth, and — in real interactions — personality and behaviour affect attractiveness ratings substantially. Studies find ratings of the same face change markedly with expression.

**Individual variation is large.** Averaged across many raters, patterns appear; any individual's preferences deviate considerably.

**Beware overclaiming.** Face-perception research has had replication problems, and "golden ratio" claims have no scientific basis.

Question 2

Do we really choose partners like our parents?

Accepted Answer

There is some real evidence behind the idea, and it is much weaker and much less mystical than the popular version — which treats it as a psychological compulsion to recreate childhood. What the

Question 3

Do couples really start to look alike?

Accepted Answer

The famous finding has not held up well, and the story of its unravelling is a good illustration of how research gets corrected. The original study. In 1987, Robert Zajonc and colleagues published

Question 4

Why do siblings turn out so differently?

Accepted Answer

Because the things that make people different are largely not the things siblings share — and this is one of the more counterintuitive findings in behavioural genetics. What the research shows.

Question 5

Do opposites really attract?

Accepted Answer

Largely no. It is one of the most repeated claims about relationships and one of the least supported — the research consistently points the other way. What the evidence shows. Decades of work on

Question 6

Why do we compare ourselves to other people?

Accepted Answer

Because there is frequently no objective standard available, and comparison is how the mind establishes where it stands. It is an automatic evaluative process rather than a character flaw — which

Question 7

Why do we like people who like us?

Accepted Answer

Reciprocal liking is one of the more robust findings in social psychology: learning that someone likes you substantially increases how much you like them, often more than similarity or attractiveness
