The Last Thing Gets the Weight

You’re reviewing someone’s performance.

Most of the year was steady.

Then something happened recently.

---

Not necessarily bigger.
Just more recent.

---

And almost without noticing,

it starts to carry more weight.

---

You see the same pattern in projects.

Months of consistent progress.

Then a recent delay.

---

Nothing about the timeline changed.

But the emphasis did.

---

This isn’t a mistake.

It’s how memory works.

Recent information is easier to access,
so it quietly becomes more influential.

---

At work, this shows up in subtle ways:

Performance reviews
Project narratives

Post-incident discussions

---

Not as a bias we don’t understand,

but as a shift we don’t always see happening.

---

A small check helps:

“Am I weighting the full timeline,
or just what’s most present in my mind?”

---

Because often,

what carries the most weight
is simply what came last.
