Understand Business Like AI

Training Example: Lodash – Review the Data, Give Your Score & Compare to the Real AI Evaluation

Industry Context — Common BS Fingerprints in Software, SaaS & Tech Products
Generic Claims: the all-in-one platform, trusted by thousands of companies, increase productivity by X percent, save hours every week…
Red Flags: AI claims without explaining what the AI does, customer logos without case study or testimonial evidence, no live product access or demo, SOC 2 claims without audit period or report availability…
Semantic Drift Patterns: homepage claims AI-powered but product is rules-based, claims enterprise-grade but pricing page shows startup tiers only, homepage shows Fortune 500 logos but case studies are small businesses, claims all-in-one but integration page shows critical missing pieces…
Proof Expectations: live product demo or free trial access, specific feature documentation with screenshots, verified customer logos with published case studies, third-party review scores on G2, Capterra, or TrustRadius…

Lodash

[H2] “Array” Methods
[H3] _.chunk(array, [size=1])
source npm packageCreates an array of elements split into groups the length of size. If array can't be split evenly, the final chunk will be the remaining elements.
[H4] Since
3.0.0
[H4] Arguments
array (Array): The array to process.[size=1] (number): The length of each chunk
[H4] Returns
(Array): Returns the new array of chunks.
[H4] Example
_.chunk(['a', 'b', 'c', 'd'], 2);// => [['a', 'b'], ['c', 'd']] _.chunk(['a', 'b', 'c', 'd'], 3);// => [['a', 'b', 'c'], ['d']]
[H3] _.compact(array)
source npm packageCreates an array with all falsey values removed. The values false, null, 0, -0, 0n, "", undefined, and NaN are falsy.
[H4] Since
0.1.0
[H4] Arguments
array (Array): The array to compact.
[H4] Returns
(Array): Returns the new array of filtered values.
[H4] Example
_.compact([0, 1, false, 2, '', 3]);// => [1, 2, 3]
[H3] _.concat(array, [values])
source npm packageCreates a new array concatenating array with any additional arrays and/or values.
[H4] Since
4.0.0
[H4] Arguments
array (Array): The array to concatenate.[values] (...*): The values to concatenate.
[H4] Returns
(Array): Returns the new concatenated array.
[H4] Example
var array = [1];var other = _.concat(array, 2, [3], [[4]]); console.log(other);// => [1, 2, 3, [4]] console.log(array);// => [1]
[H3] _.difference(array, [values])
source npm packageCreates an array of array values not included in the other given arrays using SameValueZero for equality comparisons. The order and references of result values are determined by the first array.Note: Unlike _.pullAll, this method returns a new array.
[H4] Since
0.1.0
[H4] Arguments
array (Array): The array to inspect.[values] (...Array): The values to exclude.
[H4] Returns
(Array): Returns the new array of filtered values.
[H4] Example
_.difference([2, 1], [2, 3]);// => [1]
[H3] _.differenceBy(array, [values], [iteratee=_.identity])
source npm packageThis method is like _.difference except that it accepts iteratee which is invoked for each element of array and values to generate the criterion by which they're compared. The order and references of result values are determined by the first array. The iteratee is invoked with one argument:(value).Note: Unlike _.pullAllBy, this method returns a new array.
[H4] Since
4.0.0
[H4] Arguments
array (Array): The array to inspect.[values] (...Array): The values to exclude.[iteratee=_.identity] (Function): The iteratee invoked per element.
[H4] Returns
(Array): Returns the new array of filtered values.
[H4] Example
_.differenceBy([2.1, 1.2], [2.3, 3.4], Math.floor);// => [1.2] // The `_.property` iteratee shorthand._.differenceBy([{ 'x': 2 }, { 'x': 1 }], [{ 'x': 1 }], 'x');// => [{ 'x': 2 }]
[H3] _.differenceWith(array, [values], [comparator])
source npm packageThis method is like _.difference except that it accepts comparator which is invoked to compare elements of array to values. The order and references of result values are determined by the first array. The comparator is invoked with two arguments: (arrVal, othVal).Note: Unlike _.pullAllWith, this method returns a new array.
[H4] Since
4.0.0
[H4] Arguments
array (Array): The array to inspect.[values] (...Array): The values to exclude.[comparator] (Function): The comparator invoked per element.
[H4] Returns
(Array): Returns the new array of filtered values.
[H4] Example
var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]; _.differenceWith(objects, [{ 'x': 1, 'y': 2 }], _.isEqual);// => [{ 'x': 2, 'y': 1 }]
[H3] _.drop(array, [n=1])
source npm packageCreates a slice of array with n elements dropped from the beginning.
[H4] Since
0.5.0
[H4] Arguments
array (Array): The array to query.[n=1] (number): The number of elements to drop.
[H4] Returns
(Array): Returns the slice of array.
[H4] Example
_.drop([1, 2, 3]);// => [2, 3] _.drop([1, 2, 3], 2);// => [3] _.drop([1, 2, 3], 5);// => [] _.drop([1, 2, 3], 0);// => [1, 2, 3]
[H3] _.dropRight(array, [n=1])
source npm packageCreates a slice of array with n elements dropped from the end.
[H4] Since
3.0.0
[H4] Arguments
array (Array): The array to query.[n=1] (number): The number of elements to drop.
[H4] Returns
(Array): Returns the slice of array.
[H4] Example
_.dropRight([1, 2, 3]);// => [1, 2] _.dropRight([1, 2, 3], 2);// => [1] _.dropRight([1, 2, 3], 5);// => [] _.dropRight([1, 2, 3], 0);// => [1, 2, 3]
[H3] _.dropRightWhile(array, [predicate=_.identity])
source npm packageCreates a slice of array excluding elements dropped from the end. Elements are dropped until predicate returns falsey. The predicate is invoked with three arguments: (value, index, array).
[H4] Since
3.0.0
[H4] Arguments
array (Array): The array to query.[predicate=_.identity] (Function): The function invoked per iteration.
[H4] Returns
(Array): Returns the slice of array.
[H4] Example
var users = [  { 'user': 'barney',  'active': true },  { 'user': 'fred',    'active': false },  { 'user': 'pebbles', 'active': false }]; _.dropRightWhile(users,

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

18 BS / 100

Lodash is the antithesis of business bullshit, replacing persuasive adjectives with functional code and gzipped byte counts. It scores points only for its lack of modern structured data and the presence of unlinked aggregate metrics. It is a utility tool that correctly assumes its audience values documentation over decoration.

Implement SoftwareSourceCode and WebAPI schema to bridge the identity gap and provide machine-readable authority. Replace the static review counts with live-linked stats from npm or GitHub to neutralize trust theatre penalties. Ensure the ‘modern’ environment support list is updated to include the most recent 2026 browser versions to avoid being perceived as aging. Add sameAs links to the ‘Contributing’ or ‘Support’ sections to provide a digital footprint for the core maintainers.

Lodash is a textbook example of a developer-focused utility library within the Software and Tech industry. The content perfectly aligns with this classification, focusing on implementation details, module formats, and browser compatibility rather than high-level business outcomes.

“The score of 18 is exceptionally low, driven primarily by the high information density and perfect semantic coherence between the homepage and documentation. The points earned in Trust and Proof (8/20) are due to the automated detection of unlinked metrics, while the Identity and Authority points (4/15) stem from the lack of structured schema data. This site represents a gold standard for technical substance.”
