Conditional perfect and mixed perfect

Lesson 04 mapped the full conditional terrain. This lesson zooms into a single, especially rich corner: the counterfactual continuous and mixed perfect constructions that surface in AmE memoir, personal essay, therapy talk, and longform journalism. These are the constructions that allow speakers and writers to inhabit imagined life paths — the relationship not pursued, the career not chosen, the city not moved to — and to compare them with the actual present.

The core forms are would have been doing (and its modal siblings could have been doing, might have been doing, should have been doing) and the mixed perfect structure that combines past unreal antecedent with future-in-the-past unreal consequent: If I hadn’t seen her on the train that morning, I wouldn’t be married now. Both depend on a complex chain of auxiliaries that is grammatically heavy but discursively essential at C2.

This lesson covers (1) would have been doing and its discourse function in AmE memoir, (2) the four-modal family — would/could/might/should have been doing, (3) mixed perfect across all permutations of time, (4) the AmE therapy and personal-essay register of these forms, and (5) the residual Russian-speaker traps with auxiliary order and aspectual choice.

Would have been doing — the counterfactual life path

The form would + have + been + V-ing combines:

• would (modal — unreal)
• have (perfect aspect)
• been (passive participle of be, providing the auxiliary stack)
• V-ing (progressive aspect — ongoing activity)

Examples

• If I had taken that job in Seattle, I*‘d have been raising** the kids in the Pacific Northwest.*
• If she had stayed in academia, she*‘d have been teaching** at Stanford for the past fifteen years.*
• If we hadn’t bought this house, we*‘d still have been renting** in the Mission District.*
• If you hadn’t called when you did, I*‘d have been boarding** the wrong flight.*

What the form does

It names a counterfactual ongoing activity — an action that would have been in progress (over a span of time, or at a particular past or present moment) if a past hypothetical had been true.

Compare with the non-continuous counterfactual:

• If I had taken that job, I would have moved to Seattle. (completed counterfactual event)
• If I had taken that job, I would have been raising the kids in Seattle. (counterfactual ongoing activity)

The continuous foregrounds duration, habit, or process; the simple foregrounds completed event.

Why this form is dense in AmE memoir

The personal-essay and memoir genres in AmE — David Sedaris, Mary Karr, Maggie O’Farrell (BrE adjacent), Cheryl Strayed, Anthony Doerr — depend on imagined-counterfactual reflection. Would have been doing is the canonical form for the life I didn’t lead. A typical memoir paragraph:

If I hadn’t moved to New York that summer, I would have been teaching high school English in Pittsburgh for the past twenty years. I would have been grading papers on the same green sofa. I would have been hosting Thanksgiving for my parents and my brother and his wife. I would have been a different person — duller, probably, but maybe happier.

Four counterfactual continuous clauses in a paragraph. Each names an ongoing activity from the unfollowed life path. The cumulative effect is wistful, regretful, contemplative — the signature register of AmE confessional memoir.

The four-modal family

The same have + been + V-ing stack combines with four modals, each marking a different reality status:

Could have been doing

Marks a counterfactual possibility — what was within reach but didn’t happen:

• I could have been running my own firm by now. (possibility — was within reach)
• He could have been earning twice what he’s earning at his current job.
• If the school had hired her, she could have been teaching for ten years.

Could have been doing often carries a regret tone — the missed possibility.

Might have been doing

Weaker than could have — the possibility was less assured:

• If the war had ended differently, our grandparents might have been raising their children in Riga.
• She might have been thinking about resigning even before the scandal broke.

Might have often marks conjecture about the past as well as counterfactual:

• He didn’t answer the phone. He might have been sleeping. (= it’s possible he was sleeping)

This dual reading (counterfactual vs conjectural past) is one of the trickiest distinctions in the modal-perfect-continuous family.

Should have been doing

The regret/obligation modal in perfect continuous:

• I should have been studying for the bar that summer. (= I had reason to and didn’t)
• We should have been preparing for this for months. (regret + obligation)
• The IT team should have been monitoring the system more closely.

Should have been doing is affect-loaded: it carries regret, blame, or self-criticism. Heavily used in AmE post-mortem analyses, both personal and institutional.

Mixed perfect — past antecedent, present consequent

The classic if I had X, I would Y pattern (lesson 04) takes a more nuanced form when the past hypothetical has present consequences:

If I hadn’t… I wouldn’t be…

• If I hadn’t seen her on the train that morning, I wouldn’t be married now.
• If we hadn’t taken the early flight, we wouldn’t be home yet.
• If she hadn’t gotten the scholarship, she wouldn’t be at Yale today.

Schema

This is a specific mixed conditional: past counterfactual antecedent → present counterfactual consequent. The grammar combines past perfect (in the antecedent) with would + present (in the consequent).

Why this form is dense in AmE personal narrative

Every life story has these mixed conditionals at its hinges. If I hadn’t gone to that party, I wouldn’t be sitting across from you now. If she hadn’t called that morning, I wouldn’t be writing this. The form is the grammar of fateful coincidence and gratitude/regret narratives.

Mixed perfect with continuous consequent

Combine the mixed conditional with the counterfactual continuous:

• If I hadn’t moved to LA, I’d still be teaching at that school in Pittsburgh. (present unreal state)
• If I hadn’t moved to LA, I’d still be teaching there. (= present continuous unreal)
• If I hadn’t moved to LA, I’d have been teaching there for twenty years by now. (perfect continuous unreal — duration up to present)

These three are subtly different:

C2 control includes choosing among these by the precise temporal claim being made.

Modal stacking in the counterfactual continuous

In formal AmE prose (especially journalistic and academic), the counterfactual continuous can stack with passive:

• Had the policy been implemented earlier, the rates would have been being monitored for years already.
• The patient could have been being treated under a different protocol if the diagnosis had been made sooner.

This is the densest auxiliary chain English permits (see lesson 06 on modal stacking). The chain: modal + have + been + being + V3. Rare in speech, intelligible in formal writing.

Would vs would have — the temporal split

A common source of error: choosing between would V (present counterfactual) and would have V3 (past counterfactual).

Examples

• If I won the lottery tomorrow, I would buy a house in Maine. (present/future unreal)
• If I had won the lottery, I would have bought a house in Maine. (past unreal)
• If I had won the lottery five years ago, I would have been living in Maine ever since. (past unreal → past-to-present unreal continuous)
• If I had won the lottery five years ago, I would be living in Maine now. (past antecedent → present unreal state)

The four-way distinction is essential.

The AmE memoir/therapy register

Personal essay and longform AmE journalism — and the entire genre of personal essay published in The Atlantic, The New Yorker, Harper’s, Granta (American or American-style) — leans heavily on these counterfactual continuous and mixed perfect forms.

Therapy talk

• If I had stayed in that marriage, I would have been losing pieces of myself every year.
• If she hadn’t said what she said that afternoon, I’d still be the person I was at twenty-five.
• I should have been listening to my body for years. I wasn’t.

The therapy register depends on these forms because therapy is largely about examining the unlived life — the alternative paths, the missed warnings, the regret structures.

Personal-essay register

David Sedaris, Joan Didion, Mary Karr, Anne Lamott, Maggie Nelson, Sarah Manguso, Leslie Jamison — all reach for would have been doing repeatedly. The form is the genre’s grammatical fingerprint.

AmE notes

• Would have been doing is heavily used in AmE personal essay, memoir, and op-ed reflection.
• Could have been doing carries regret; might have been doing carries weaker possibility or conjecture.
• Should have been doing is the AmE post-mortem grammar — used in incident analysis, performance reviews, and personal self-criticism.
• Mixed perfect (If I hadn’t… I wouldn’t be…) is the AmE narrative-hinge construction.
• AmE casual speech tolerates If I would have known in the antecedent (lesson 04); C2 writing keeps the pluperfect If I had known.
• Would have been being V3 is rare even in formal AmE but appears in long-form journalism describing extended past processes.

Pragmatic note — the cost of heavy counterfactual

A paragraph saturated with would have been doing reads as regretful and brooding. This is appropriate to memoir but often inappropriate to journalism, op-ed argument, and business writing. The form carries strong affect; deploy it where the affect is the point.

When the same content can be expressed without counterfactual, consider doing so:

• Counterfactual-heavy: If I had stayed, I would have been raising the kids in Pittsburgh; I would have been teaching at the same school; I would have been hosting Thanksgiving every year.
• Trimmed: I’d have stayed in Pittsburgh — kids, school, Thanksgiving, the whole shape of a life I never had.

The second packs more in fewer words and uses the counterfactual once for marked effect.

Common Russian-speaker mistakes

1. Missing been in the stack: I would have raising the kids in Seattle → I would have been raising the kids in Seattle. The full chain is would + have + been + V-ing; dropping been breaks the construction.
2. Wrong auxiliary order: I would been have raising → I would have been raising. Order is fixed: modal + have + been + V-ing.
3. Calquing Russian бы with English would in antecedent: Если бы я знал → If I would know → If I had known. Бы is the counterfactuality marker; English uses tense backshift.
4. Confusing would (present unreal) with would have (past unreal): If I won the lottery, I would have bought a house (mismatched — antecedent is present, consequent is past) → If I won the lottery, I would buy a house OR If I had won the lottery, I would have bought a house.
5. Russian aspectual leak: choosing would have done (perfective) when AmE wants would have been doing (imperfective continuous). If I had moved, I would have lived in Maine (single state) vs If I had moved, I would have been living in Maine (extended ongoing state — more natural for the imagined-life-path reading).
6. Treating should have been doing as obligation rather than regret: I should have been studying for the bar that summer — this carries regret/self-criticism, not present obligation. Russian Я должен был учиться is closer; English I should have been studying foregrounds the regret.
7. Heavy counterfactual where simple past works: If I hadn’t taken the job, I would have been living in Pittsburgh (extended counterfactual) — overkill if the propositional claim is “I would have lived in Pittsburgh” with no extended-ongoing emphasis. Trim to I would have lived in Pittsburgh unless the ongoing-duration aspect is the point.

Summary

• Would have been doing is the counterfactual continuous — a counterfactual ongoing activity in past or extended into present.
• Modal-perfect-continuous family: would/could/might/should have been V-ing. Each carries different reality status and affect.
• Mixed perfect: past unreal antecedent + present unreal consequent — If I hadn’t seen her, I wouldn’t be married now.
• Four temporal-reality slots: would V (present), would have V3 (past), would be V-ing (present ongoing), would have been V-ing (past ongoing or accumulated to present).
• Should have been doing is the AmE post-mortem/regret form; heavily used in incident analysis and personal self-criticism.
• This form-family is the grammatical fingerprint of AmE memoir and personal essay.
