1Ethical Conduct of Engineers – Key Concepts (Lectures 31–32)

🔑 What Makes a Good Engineer?

A good engineer goes beyond technical skill — they uphold ethical values and take responsibility for the impact of their work on society. Key questions to reflect on:

  • What values underlie engineering practice today?
  • Which values are specifically ethical values?
  • How do these values shape who you become as a professional?

🔑 Religious vs. Ethical Values — How Are They Related?

Most major world religions uphold both religious and ethical standards simultaneously. Key points:

  • Ethical standards from religion apply to moral agents — their character traits, motives, and actions.
  • Religions differ in emphasis: some focus on individual spiritual virtue, others on family structure or communal practice.
  • Religions often provide personal guidance on what individuals are "called" to do — overlapping significantly with professional ethics.
💡 Key Insight: Religion and ethics are related but not identical. Both guide conduct, but ethical reasoning in engineering must be objective, evidence-based, and universally applicable — beyond any single faith tradition.

🔑 Ethical Subjectivism — What Is It and How Do We Handle It?

Ethical Subjectivism: The view that whether an act is right or wrong is determined solely by whether the agent performing it believes it to be right or wrong — without any objective standard.

This is problematic because it makes ethics entirely personal with no shared accountability. To tackle it, we use established ethical theories:

TheoryCore Idea
UtilitarianismAn act is right if it produces the greatest good for the greatest number.
Duty Ethics (Deontology)Certain acts are inherently right/wrong, regardless of consequences.
Rights EthicsActs must respect fundamental human rights.
Virtue EthicsFocus on developing good character traits (virtues) rather than following rules.

🔑 Ethical Judgments vs. Intuition

Intuition: The ability to immediately recognise what is going on in a situation — often a product of training or experience.
Ethical Judgment: Requires explicit reasons/evidence or argument to demonstrate that something is ethically acceptable or desirable.

What distinguishes a judgment from intuition is the availability of explicit reasons or identifiable evidence. Ethical evaluation is a judgment about how good or bad something is, ethically speaking.


🔑 What Makes an Act Morally Justified?

A reasoned moral judgment will consider some or all of the following criteria:

  • ✅ The act produces good consequences (or avoids bad ones)
  • ✅ It respects rights rather than violating them
  • ✅ It fulfills obligations rather than shirking them
  • ✅ It honors agreements and promises
  • ✅ It fosters virtues (positive character traits) rather than vices
⚠️ Exam Note: The course specifically states that consequences upon people's character (virtues/vices) are considered separately from other consequences. All the above together make an act morally justified — this is the accepted answer for Assignment Q10.

🔑 Justifications vs. Excuses for an Action

Consider a scenario where you are criticised for how you installed a component:

ResponseTypeWhy
"That's what the safety code required."JustificationShows the act was correct and required
"I was given the task late — no time to do it differently."ExcuseAcknowledges wrong but reduces blame (not in full control)
"This was my first time, I made mistakes."ExcusePartial reduction of blame — lack of control/experience
"If you don't like it, do it yourself."NeitherDeflection — no ethical weight
2Central Professional Responsibilities of Engineers (Lectures 32–33)

🔑 What Makes a Professional Trustworthy?

In today's era of specialised knowledge, society depends on professionals — especially engineers — for safety, health, and well-being. Two benchmarks of trustworthiness:

1. Exercising Moral Judgment

Taking into account a range of factors, applying professional knowledge, and devising the best course of action in the circumstances.

2. Taking Moral & Professional Responsibility

Considering all competing factors that might influence the outcome and owning accountability for results.

💡 Trustworthy practice requires sustained attention to the well-being of others AND the knowledge/wisdom to promote or safeguard that well-being.

🔑 Case Study: Captain Sullenberger — An Exemplary Response

🛬 Landing a Disabled Plane (US Air Flight 1549, Jan 15, 2009)

Within 90 seconds of takeoff, both engines were disabled by a bird strike. Captain "Sully" Sullenberger took control, decided against returning to the airport, and successfully ditched the plane in the Hudson River — with no loss of life. He demonstrated practical wisdom, courage, and steadfastness, and was last to exit the aircraft.

Lesson: He integrated theoretical knowledge, practical experience, and ethical responsibility — his first professional duty was the safety of those on board.


🔑 Moral Responsibility vs. Official Responsibility

Moral Responsibility: A person must exercise judgment and care to achieve or maintain a desirable state of affairs in matters entrusted to them.
Official (Job) Responsibility: Clearly stated duties defined in a job description or position — what one is explicitly told to do.
DimensionMoral ResponsibilityOfficial Responsibility
SourceEthics, professional standardsJob description, employer directives
ScopeBroader — may go beyond the jobLimited to defined duties
ExampleReporting a safety hazard not in your briefSubmitting the project report on time
⚠️ Critical Point: Moral responsibility does NOT reduce to official responsibility. "I was just doing my job" is NOT a valid ethical excuse for unethical behaviour in adults.

🔑 Official vs. Moral Responsibility: Key Distinction

S1 in the assignment stated: "Official responsibility and moral responsibility are very similar in nature and can be used interchangeably." — This is FALSE. They are distinct concepts. The correct combination from the assignment is:

  • S1 — False (they are NOT interchangeable)
  • S2 — True (moral responsibility requires exercising judgment and care)
  • S3 — True (moral responsibility cannot simply be transferred)
  • S4 — False (official responsibility CAN have immoral connotations)

🔑 What a Trustworthy Structural Engineer Must Check

Before greenlighting any project, a trustworthy structural engineer must verify:

  • Proficiency in structural design; understanding of building material characteristics
  • Understanding of traffic demands relative to material strength
  • Understanding of environmental implications of the work
  • Estimate of likelihood and severity of natural threats (earthquakes, hurricanes, etc.)
  • Public safety, public convenience, and environmental protection concerns
  • Other technologies that might influence the structure's use
  • Potential intentional threats (sabotage, terrorism)
⚠️ Assignment Q6 trap: "An estimate of the likelihood and severity of earthquakes is NOT required as such natural disasters are less frequent" — this is the INCORRECT statement. Engineers MUST estimate these risks. Answer: (d)

🔑 Responsibility for Safety — The Emerging Consensus

Engineering codes of ethics from five major societies — ASCE, ASME, AIChE, NSPE, and NCEES — all state:

"Engineers, in the fulfillment of their professional duties, shall hold paramount the safety, health, and welfare of the public."

Similar to medicine's "First, do no harm" — engineers must first ensure a system doesn't do what you don't want it to do (safety), then ensure it does what you want (performance).


🔑 Causal vs. Moral vs. Professional Responsibility

TypeMeaningExample
CausalYou physically caused the outcomeYou designed the faulty component
MoralYou have an ethical obligation to act/preventYou must report the hazard even if not your job
ProfessionalArises from special knowledge of your professionAs a licensed engineer, you are responsible for public safety
⚠️ Assignment Q3: The state environmental engineer's scenario — the correct answer is (d) Both B & C — both moral AND professional responsibility apply, not just professional (c) alone.

🔑 Whistle-Blowing

Whistle-Blowing: An engineer taking a safety concern outside their organisation when internal channels have failed to address it.

Key conditions for whistle-blowing to be justified:

  • Concerns have already been reported to immediate superiors with no satisfactory response within a reasonable time ✅
  • There is clear evidence of wrongdoing, properly documented
  • A significant threat to human life or health exists
  • The person is a current or former employee OR has a close link to the organisation
⚠️ Whistle-blowing is not justified when: no potential harm is identified; data is inadequate and not properly documented; it might jeopardise national interests without sufficient cause.

Whistle-blowing always marks organisational failure — the ideal is that safety concerns are resolved internally before escalation becomes necessary.


🔑 Software Engineers and Safety

For software engineers, the central responsibility is framed differently than for civil/mechanical engineers:

  • The core concern is bugs and glitches rather than safety hazards per se
  • This is because bugs' harmful effects depend heavily on the broader system context — harder to predict than mechanical failures
  • A software engineer's responsibility is best described as: avoid all errors that produce bugs/glitches — rather than only preventing specific safety-threatening bugs
3Rights & Responsibilities Regarding Intellectual Property Rights (Lectures 34–35)

🔑 What Is Intellectual Property?

Intellectual labour involved in creating research, artistic, and technological works provides the basis for property rights. Key distinctions:

Property Right (Patent/Copyright)

The legal right to control use, sale, or reproduction of the work. Belongs to employer/client if work was done for pay.

Credit (Attribution)

Acknowledgement of who actually created or invented the work. Belongs to the actual creator regardless of who owns the IP.


🔑 Patent

Patent: A contract between the individual inventor and society (all others). The inventor receives exclusive rights for a period; in return, the invention is publicly disclosed.

Patent protects the invention/process itself. Under industrial design patent, only the non-functional ornamental/aesthetic features can be patented — not functional features.

⚠️ Assignment Q9 — Tea Cup Example: A tea cup has functional features (hollow receptacle, handle) AND unique ornamentation. Under industrial design patent, only the ornamentation on the body can be patented — answer: (a)

🔑 Copyright

Copyright: A legal right to exclusive publication, production, sale, or distribution of a work. Protects the expression of an idea — NOT the idea itself.
  • Typically held by author, composer, or publisher
  • Can be assigned or inherited — copyright holder need not be the original creator
  • Ideas cannot be copyrighted — only their specific expression
  • Fair Use: Copying is permissible if it does not undermine the copyright holder's interests AND is in the public interest (e.g., education)

🔑 NSPE Code of Ethics on Intellectual Property

The National Society of Professional Engineers (NSPE) code on IP addresses both ownership AND fair credit. Key obligations:

  • Engineers shall name individuals responsible for designs, inventions, or other accomplishments whenever possible
  • Client-supplied designs remain the client's property — cannot be duplicated without permission
  • Before undertaking work that may result in patents/copyrights, enter a clear agreement regarding ownership
  • Designs, data, and records exclusively related to an employer's work are the employer's property
💡 Assignment Q8: The NSPE's code of ethics on intellectual property gives standards for fairly crediting others as well — going beyond just proprietary/ownership interests. Answer: (a) National Society of Professional Engineers

🔑 NCEES — Full Form (Frequently Tested!)

NCEES = National Council for Engineering Examiners and Surveyors

One of the five engineering societies whose code of ethics mandates holding public safety paramount.


🔑 Proprietary Knowledge — What Is It?

Information can be proprietary if it is:

  • A trade secret (confidential business plan, proprietary process)
  • A patented device or process
  • Copyrighted code

Engineers and computer professionals must distinguish between standard design elements (freely usable) and customised, patented, or confidential knowledge belonging to a specific employer or client.


🔑 Whistle-Blower Protection and Anti-Corruption

Assertion: Whistle-blower protection is crucial for the success of anti-corruption detection.
Reason: Retaliation against whistle-blowers can happen regardless of the channels they use to report corruption, so the relevant organisation should provide protection.
💡 Both A and R are true, AND R is the correct explanation of A. Answer: (a)
4Assignment 7 — Question-Wise Analysis
Q1 — Patent as a Contract

Statement: Patent is a contract between the individual (inventor) and the society (all others).

Answer: (a) True — A patent is precisely this: exclusive rights in exchange for public disclosure.

Q2 — Whistle-Blower Assertion-Reason

Assertion: Whistle-blower protection is crucial for anti-corruption detection.
Reason: Retaliation can occur regardless of reporting channels.

Answer: (a) — Both A and R are true, and R correctly explains A.

Q3 — Type of Responsibility (Environmental Engineer)

A state environmental engineer is asked to assess if a power plant meets Clean Air Act requirements (sulfur dioxide, nitrous oxide reduction). What type of responsibility is this?

Answer: (d) Both B & C — Both Moral responsibility and Professional responsibility. The engineer has both an ethical duty (moral) and a knowledge-based duty (professional) to ensure public safety.

Q4 — True/False Combination (S1–S4)
  • S1: Official and moral responsibility are interchangeable → FALSE
  • S2: Moral responsibility requires judgment and care → TRUE
  • S3: Moral responsibility cannot be simply transferred → TRUE
  • S4: Official responsibility can never have immoral connotations → FALSE

Answer: (b) S1-F, S2-T, S3-T, S4-F

Q5 — Full Form of NCEES

Answer: (c) National Council for Engineering Examiners and Surveyors

Q6 — Trustworthy Structural Engineer (Exception)

A trustworthy structural engineer must check everything EXCEPT:

Answer: (d) — "An estimate of the likelihood and severity of earthquakes is NOT required as natural disasters are less frequent." This is false — engineers MUST estimate such natural risks.

Q7 — Justified Whistle-Blowing

Whistle-blowing is justified when:

Answer: (a) — Concerns have been reported to immediate superiors and no satisfactory response was received within a reasonable time. This is the primary trigger for justified whistle-blowing.

Q8 — NSPE Code on IP

Which organisation's code of ethics on intellectual property gives standards for fairly crediting others beyond proprietary interests?

Answer: (a) National Society of Professional Engineers (NSPE)

Q9 — Industrial Design Patent (Tea Cup)

A tea cup has a hollow receptacle (functional), a handle (functional), and unique ornamentation (aesthetic). Which part can be patented under industrial design patent?

Answer: (a) Only the ornamentation on the body — Industrial design patents cover aesthetic/ornamental features, not functional ones.

Q10 — Identifying the Erroneous Statement (S1–S3)
  • S1: Intuition is the ability to immediately recognise what is going on → Correct definition
  • S2: Intuition may result from training/experience; ability to recognise without articulating → Correct
  • S3: A reasoned judgment about moral justification considers consequences, rights, obligations, agreements, and promises → Correct and complete

Answer: (d) None of the above — All three statements are correct.

📝 Exam Strategy Tips

  • Watch for assertion-reason questions — verify both A and R independently, then check if R explains A.
  • For true/false combination questions, eliminate clearly wrong options by checking each statement carefully.
  • In responsibility-type questions, check if both moral AND professional apply — often the answer is "both."
  • For industrial design patent questions, remember: function cannot be patented, only appearance.
  • NCEES full form is a favourite factual question — memorise it exactly.
